Both systems would need to have a clutch to disengage the electric motor from the other driver. (pulley or turbine) The turbo is a pretty hot place for a clutch assembly and electric motor too. (Clutch may not be needed on the turbo, as it would help scavenge exhaust with the electric motor)
The added complexity of a supercharger (gearbox, clutch, oil, etc.) is not worth it, as more money should just be put into an electric compressor/supercharger.
A true OEM electric supercharger would have the proper components that would make the standard supercharger/turbocharger pieces unnecessary. This is getting pretty off topic though, so we'll leave it at that.
