Pretty much impossible even for the genesis; GameGear has a pallette of 4,096 colors with 32 onscreen. Genesis only has a palette of 512.
SMS would practically be nothing more than putting sega master contacts in an empty genesis cart as a pass-through, though, and of course a little hardware to connect the SMS slot to the genesis one. Nobody gives a shit about the cards, forget them.

Yeah, the board from viletim that the fellow in that video used is very well done and really the best way to get your GG consolized. His prices on the board are actually really really reasonable considering the amount of time he put into them, and if you've got decent soldering skills you can get the whole thing put together pretty quickly.
