I think this is simple and effective, but has two weak points. Firstly the difference between double and 2NT is not clear - do you double with good diamonds, so 2NT implies exactly a single stopper? I would rather pass more often and bid 2NT less often.

Double if it looks probable we can score better defending than playing NT from own side: depends a lot on zone as well as our evaluation of the diamonds holding and of course partner is involved in the choice. I think pass will be at least as well loaded as 2NT, considering the frequency of 5-card spades with no stopper.

Secondly the auction 1♠-(P)-2♣*-(2♦); 3♣ is not an economic use of bidding space, even with 2/1 GF. I think it would be easiest to play 'system on', so "If you would have responded 3♣, do so now as well" but slightly better to move some of those hands to pass as well, e.g. the 5=1=3=4 minima can pass then support clubs.

I think this depends mainly upon the quality of the 4+ clubs, if the suit is stopped then they should be shown. I agree that weak 4 or even 5 card could pass.
