In-board motors, one per wheel, have all those advantages you state for wheel motors, but none of the disadvantage of excessive unsprung weight. Additionally, a bad pothole means only replacing a cheap wheel and not an expensive motor.
Steel wheels on a 112kW car do not weigh near 43 kg. Don't fall for the empty promises.

They'll never be cost-effective for freeway-capable cars. I'll make a long term bet on it with anybody.
EDIT: your linked study says you can add features to somewhat make up for the excessive unsprung weight. Sure, which is why I'm pointing out not that it can't be done, but that it costs more for the same performance and always will (at Earth gravity and freeway speeds).
