(or you could get in touch with me about having a run of buttons made in those two colors, and not destroy your controllers... i'm more than open to custom orders in bulk, might be cheaper too)
Kitsch, I think it'd be a fantastic idea if you sold SNES colored buttons. I have a gameboy myself that has some SNES buttons from a broken controller, and it can be a pain to get the plastic tabs cut down to the right size. But it was worth it because it looks great! Vile, you're right about the recessed buttons being desirable too. If these become available, whether it be through you, Vile, or through Kitsch's store, I'd be more than willing to buy some. I think Kitsch's idea of buying in bulk from him may be best because 1. people will be assured no working controllers were destroyed to make their gameboy prettier and 2. they'll be shiny and new!
