Anyone who thinks this is even a remote possibility has clearly never worked on an EV or any modern vehicle.
The only possibility is a tiny air-cooled 'helper motor' a-la Toyota Prius AWD, but the vehicle would have had to be designed from the start for such a system. The HV battery would need to have a dedicated output for that system, the LV harness would need provisions for the large harness, the chassis designed for that rigidity and half shafts... All of that would add significant cost to every vehicle. And if you wanted to add a full-sized motor, then you would need to re-design the cooling system to accommodate nearly double the heat load.
