The unsprung weight is not that big a deal, really the inertia from the rotating tire is so great that the addition of some stationary components in the middle don't add that much.

While the angular momentum of wheels and tires does make a pretty large contribution to overall vehicle inertia, the fact that the wheel is rotating won't influence the specific issue of unsprung mass one way or another.
