Well I suppose one probably could still design it, but like you said, it's probably not an elegant solution.

I think your powertrain calcs are probably fine, and I wouldn't worry too much about acceleration. My freshman year (2001) we ran 2 Bosch drill motors geared for 10ft/s and it worked wonderfully, 4 cims should have plenty of torque to get you by. You probably won't win a pushing match against a hardcore pushing robot, but that's what shifting transmissions are for if you chose to use them.
