Yeah man! Great idea, maybe not doable any time soon with our R&D access, but doable. Although, I am not too keen on using warm gears for anything R/C however, I just don't like them. This idea though having the diff being physically built into the motor housing is awesome, and on each end of the chassis you are saying? I don't think you would even need warm gears, as you can really do anything with motors, increase torque, lower speed, yada, yada.

Sike, ya, I think a sufficiently thick alum. plate screwed to diff housing then if the motor shaft was keyed, or squared, or splined..... then it would just slide in and be supported by the motor shaft, which because of the fact that it would be over sized from the increased size hollow shaft then it would be fine maybe.
