The SG-1000 graphics mode is more or less the same as the ColecoVision's, and nothing like it is used natively in the Genesis, so you'd be starting from near-scratch. (They even managed to screw it up on the Master System, with incorrect palette values that are hardcoded and can't be fixed.)
The best way to play SG-1000 games on US hardware is probably on the Game Gear, strangely enough -- especially now that KRIKzz has released a BIOS revision for the EverDrive-GG that sets up the TMS9918 palette correctly. (I need to check that out, as I was one of the people bugging him for it.)
Otherwise, someone would probably have to write a program to interpret SG-1000 code somehow, intercept any calls to graphics routines, and convert them to something the Genesis supports. A guy on AtariAge recently did something like that to allow RCA Studio II games to run on the Intellivision, and I'd imagine it's at least theoretically possible -- as long as the Genesis palette allows for an exact reproduction of the SG-1000 colors.
