OP, that would work if you have some kind of load balancing system in place to avoid what DonRotolo mentioned. Unfortunately, we can't do this easily in electronics due to the rules, but you might be able to explore some kind of differential or other mechanical load balancing system. This would preclude the use of a CIM on each wheel as the power would have to come from a unified source.

Of course, this is likely more trouble (or money) than its worth! Would be a great way to win an engineering award!
