While I don't know if it would make it a 'whole' lot easier
(since you need to already make your own gearboxes for swerve anyway so changing the last stage to match the motors wouldn't be that hard) The FP and Atwoods are somewhat simple to match to the FP’s as described in many documents.
It does make the design much more common as you can have 4 (or 2 of L/R) identical interchangeable modules with the same motors. I think it would make a very nice powerful swerve robot. The hardest part to swerve in my mind is the control of 4 gearboxes both in steering, power levels, and the operator control system.
If we got 4 of the same drills……. I would probably put 2 of them together on each side with the Atwoods to make a monster shifter gearbox with incredible power and redundancy. But that’s just me.
