Holy shit! Mario cart themed mods!? How awesome is that!?
Also, yeah I heard about the DC version of GTA 2 supporting PC mods as well. I think it would be great to start exploring exactly how modable it is. I know somebody made a 3D perspective mod where they mixed it with Duke Dukem. Man, I could see a camera perspective change mod and 3D car model replacements for the game. I think it could be possible to make GTA feel a little more like a proper 3rd person 3D carjacking game.

Also, porting GTA 1 to DC might actually be possible too right? At least the assets. The PSX version running on Bleem beta works really well, but obviously saves and FMV's are screwed up.
I think we might be onto something here.
