Ken... believe me, I 'get it'. I understand the problems you are attempting to solve.
In fact, I agree that adopting a SYSTEMIC artificial 2
♣ response has some merit.. it lends itself very nicely to relays, btw.
My concerns were threefold: one, that in a standard method, opting for 2
♣ without prior discussion IS seizing captaincy. It has to be.. you are lying to your partner while making what is ostensibly a natural bid: a bid that denies any significantly longer suit than
♣s. He will make his bids on a false assumption of how his hand meshes with yours. You expect to be able to control the auction, and, on many hands, you will be able to do so.. but don't kid yourself... you are 'controlling' the auction.. which is the role of captaincy.
The second branch of my concern is that 2
♣ on shortness is not a panacea. You MAY be able to control the auction, but not always. Partner may become wrongly enamoured of his hand because of clubs... or may fail to become enamoured of his hand because of spades.. and even if you dodge those bullets this time, there will later be hands on which responder holds.... clubs! and needs opener to trust that he does in order to get to the right spot.. yet, once you incorporate this short 2
♣ response, opener is going to have to be careful.
The third branch relates to your apparent assumption that 1
♠ creates nothing but problems. Heck, you even went so far as to say that a raise to 2
♠ created a problem!!! Your ideas about bidding are far different from mine if you feel that you can no longer bid intelligently, with a gf, slam-interest hand once partner reveals the double-fit via 2
♠ 
Personally, I'd be delighted. I can bid 3
♥ FORCING and natural... do you seriously tell us that this can be passed? Or I can bid a new suit... plus I have a good idea of partner's strength... the single raise to 2
♠ limits his hand far more than does any normal rebid over 2
♣.
And if he rebids either of 1N or 2
♣ (neither of which are exactly uncommon rebids) I am going to be far, far further ahead in my bidding than any who started with 2
♣ by responder.
If he rebids 2
♦, then I have a problem.. but not an insoluble one. I bid 3
♣, the worst 4SF sequence. If he bids 3
♦ (many play that the default rebid on a nightmare 2=5=4=2 or 1=5=4=3 hand with no club stop is 3
♦), I am back in the running with 3
♥. If he rebids 3
♥, I can always bid 4
♥ having expressed some interest and having shown a long
♠ suit. This is the worst of auctions, and I have personally missed a slam after this sequence (or one very close to it). But if responder has significant extras, he may be able to make a more aggressive call.. whether that be 5
♥, keycard etc.. I am not saying that responder can always overcome the problem, but i am saying that this problem does not, in my view, warrant the drastic measure of fabricating a 2
♣ response. As I hope is apparent, the 2
♣ response will actually impair your bidding on at least as many hands as it will help, and will be neutral on many more.
I didn't mention a 2
♥ rebid: it also is problematic for my approach, but so is it after 2
♣: it is far from clear what degree of fit is shown by a raise to 3
♥, as earlier posts in this forum have shown.
