What If you took an original PSX controller like this:

and put a GB micro in it?
It would be fairly simple, screen+mobo in the middle section, chopped PS boards under dpad/ action buttons, and L2=L, R2=R, L1=select, R1=start, Circle=A, X=B, Triangle=volume+, Square=volume-. Would look like a psx controller with a small widescreen in the middle. What do you all think?
