So you take away the braking effect of wheel spinup to use the motors as braking aids? Imagine a 747 with 16 large electric motors (these wheels are very heavy), all of which have to function or they are all switched off. The wheel units can get extremely hot, even glowing red hot, and the motor must survive that? As well as frequent drenching? For a very questionable saving on rubber? And at a weight penalty of several hundred kilos? I think we are talking well expensive electrical units (and incredibly tough)! No way. That's why nobody has them (or will in the foreseeable future).
