Sonic CD "homebrew" for DS?

Wouldn't it be awesome if someone made a homebrew port of Sonic CD (argubly the best Sonic game) for the DS?

It doesn't look like a whole Sega CD emulator is possible, but a homebrew version of a single game should be. There are some pretty sweet ports of Lemmings, Doom, Quake, even Quake 2 out there, and Nintendo managed to port Mario 64. So I imagine making a version of Sonic CD for the DS wouldn't be unthinkable.

I'm totally willing to work on this project with anyone interested. I have no game programming ability, but could sure do a lot of promo for the project and provide all the PR, moral and perhaps financial support for this.

Could this be doable?

Could you work on the project or continue it please?
