I'm not so sure. Sebring/Vanguard tried that in the Comuta-Cars (and maybe some Citicars). The ran forced air into the motor for cooling. It was collected in a diverter box so it could be vented to the open air in summer, or sent into the cabin for "heat" in the winter. Electric motors of course are WAY more efficient than ICEs, so there's not so much waste heat. I had a C-car in the late 1980s, and the "heater" had no cabin-warming or defrosting effect that I could discern. However, it did bring in some hot-oil stink (the seal between differential and motor always leaked a bit) and a little ozone odor. If you were using a heat pump anyway, it would probably make some sense to harvest the small amount of waste heat from the motor. Otherwise, it's probably going to help much.
