After some more thought, I guess there's 3 main requirements:
  • Spacing of the motors (easy peasy)
  • Correct alignment of both pinions on each shaft (hmm, tricky)
  • Assembly such that the pinions of each motor are in synch with every other motor (this part would be fun!)

For what it's worth, the Penguineers used a shifting design with two pinions per motor successfully in 2012. Their solution to these issues was apparently to make 4 gearboxes, one for each wheel.
