I think in principle it wouldn't be too complicated. It would only be designed to control as many motors as a person was using, so either 2 or 4 in most situations.

It effectively simulate traction control if done properly and would probably improve the efficiency of the system in wintery/slippery conditions. It would require one relatively minor change to your controller. It would need an input/output port that could communicate with the traction control system. The system would need date regarding the wheels rpms or ground speed; and would need to be able to handle a command from the traction control system which would tell the controller to ease off the power some.

The traction system controller could be low voltage so cost of building the unit would probably be low and could even work for a single drive system to avoid spinning the loan wheel. This would probably require an auxilary sensor on a different wheel to determine road speed to compare to the wheel with motor's speed.
