Inboard brakes have been done before, mostly on race cars but also some production cars. The biggest issue for production cars is packaging.
The main advantage to inboard brakes is the reduction of unsprung weight but the invention of carbon disc has reduced that advantage.
Attached are two race setups. The first is on the rear axle of a sprint car. The second is a Lotus F1 car
