Help me fix my system 1C-1H-2C in Transfer Walsh

Now I thought I was being clever when I came up with the idea of switching responder's 2♦ and 2♥ rebids here such that 2♦ shows 4+ hearts and 2♥ shows 4+ diamonds, with opener either "raising" (e.g. 1♣-1♥; 2♣-2♦; 2♥, showing a doubleton spade, or else showing max/min via 2NT/3♣.
Unfortunately, this has caused some unwanted memory strain in this rare sequence (especially since 1♣-1♦; 2♣ is completely different) and has a bit of a hole with regards to single-suited responding hands. I'm sure I could plug the hole by putting strong single-suiters into 2♦ or 2♥ and codifying the followups even further, but that would just worsen the memory problems.
So does anyone have a suggestion for simple, elegant followups in this situation? Should I make 2♥ non-forcing and 2♦ an artificial force promising nothing? Or should I give up on the ability to get out in 2♥?

I would want to know what kind of jump shifts you are playing? Weak, Strong, or Invitational? Invitational or forcing jump shifts over 1♣ might take some hands out of the 2-level transfer of 2♦ or 2♥.

The not-showing-spades-at-all kind. If responder has spades, he bids 1♥, period.

Ive seen 1N used for this then your 2S bid is overloaded or a jump to 2D/2H
Then you can have 2H nat force

It could also be 2(42)5, we have the option of showing that as a balanced hand but if the values are concentrated in the suits we would show it as unbalanced. And obviously the 2♣ rebid can also be made with more than 5 clubs, e.g. 2236.
I'm not sure what you mean by "outside your 1N rebid range", our 1NT rebid shows 17-19 balanced, and as I said, 2♣ shows 11-15 unbalanced (i.e. not 2335).

It's an interesting thought - I currently use all of 1NT/2♣/2♦ (responding to 1♣) as hands with diamonds. Perhaps my 1♠ response (4+ clubs, no major) is somewhat underloaded, and with a redistribution I could perhaps free up one of those responses to show a 5=4 majors hand (4=5 I don't really think is a problem). It's a bit too major a change for what I'm looking to do now but I would keep it in mind if I were starting over.

2d = various inv hands or just looking for the best game
... 2h = denies four hearts
... 2s = four hearts, will not have 3S
2h, 2s = less than inv, natural
2nt = GF, ask pattern
... 3c = 6+ clubs no side suit some shortage
... 3red = 4-suit
... 3s = three spades
... 3nt = 2(23)6 or 2227
3c = GF raise
3-red = natural 5/5 GF
3s = good 6+ suit GF
3nt = to play
After 1c-1h!-2c-2d!-2h!:
2s = 5-6s inv (partner can pass w/2)
2nt, 3c = natural inv
3d = 4-6 inv (natural)
3h = 5-5 natural inv
3s = 6+S strong suit inv
3nt = 5s, choice of games
After 1c-1h!-2c-2d!-2s!:
2nt,3c = inv natural
3d = inv 4/6
3h = inv 4h
3s = 6+S inv
3nt, 4h = to play (with 5s)
I'm assuming 3415 and 3406 are spade raises if too weak to reverse, so opener showing four hearts also denies three spades.

I play something almost identical to this - I like the invitational hand going through 2♦ and having two main ways to force (plus a few other specific ways).
It's ostensibly not for those who like a simple system, but it can be done in such a way that shares common principles with many other sequences.

Thanks - you somewhat missed the mark as to my personal needs, though, because you have opener showing 3 spades in several places which he can't have in my system (all the unbalanced hands with 3-card support complete the transfer for me). I'm not sure how I feel about 2NT being game-forcing, I'll have to think more about that.
Anyway, it seems there's a clear consensus that 2♥ and 2♠ should be natural and nonforcing with 2♦ as some sort of omnibus bid, so thank you all for your input on that.

1NT/2NT/3♦/3NT: 3=3=4=3 or 5♦(332) shapes various ranges - 3♦/3NT can have 4 clubs also

I acutally decided to make a weird twist in the response scheme i played over 1C to help with memory issues. At least they seem to work - the idea is borrowed from Ambra and Fantunes - that is using 2♦ and 2♥ as hearts and spades.
These transfers promise a) a weak jump shift in the suit b) a game going hand with atleast 5+
The idea is to simplify the auctions over transfer walsh on the first go. I know you can use checkback and or what not but this simplifies these auctions. This is how Fantunes have their responses over 1C as well(they have 2M as natural 5+ and GF, so this is a small modification).
Now going back to the original problem - in the given situation just use the cheapest suit as some sort of force or keep it natural. It is simpler. With 5-4 with the proposed changed you would start 1C-2H, 2S-3H showing 5-4 and game going - not perfect but simple. If you have a strong hand - I think you can still find the clubs.
As for one more - i do think your 1S is underused. You can add some hand types there.

11-15, 2-S6+C or 2-S4R5C
instead of
11-15, 6+ C or 4M5C?
Then you could play
1C-1H; 2C-2D(relay); ?:
2H/2N+: same as 2H/2N+ over 2C-2D in standard Precision, except that Opener has now already denied 3+ S
2S = 2-S4+ D, but with continuations analogous to those in standard Precision after 2C-2D; 2M

2♦ = 4+ hearts
2♥ = 6+ spades
2♠ = range ask
2NT = 3+ clubs, INV+
3♣ = 5+ diamonds, INV+ (you could make it GF if preferred and run the invites through 2♠)
3♦ = weak, nat
Such a method is not as optimized as Adam's but it is relatively easy to remember and it might be possible to rearrange it to match the 1NT structure being used, making it even easier.

1♣ - 2♦ as 5+♠4+♥ less than a 10 count, you can then get:
1♣ - 1♥ (showing spades) - 2♣ - 2♥ as natural but 10+ and F1, and only 5♠5♥ if GF as you can also play:
1♣ - 1♥ (showing spades) - 2♣ - 3♥ as 5♠5♥, invitational, NF
If you hate rebidding 2♣ on 4-5 in the minors and poor club suits you could do one of two things:
Complete the transfer to show any hand with diamonds and clubs, then use 2♦ as your forcing raise with support
OR
Open 1♦ on hands with longer clubs below reversing values and fiddle with rebids to show this hand:
1♦ - 1M - 1NT to show the longer diamonds hand to remove the need for false preference and then:
1♦ - 1M - 2♣ as the 4-5 in the minors minimum hand
Now the nice thing is you can have your relay after 1♣ - 1Red - 2♣ as 2♦ as most of the time partner will not have 4 diamonds (this can help you GF with clubs for example)
It does feel like you've overloaded your higher level bids to deal with the minors
