I would ask in the Electric Bikes subforum if it will work. And you need details as to the bike you have and the hub motor you want to use.

You will not save 1cm between a 6 and 7 speed freewheel. You “might” be able to use a 5 speed freewheel with friction shifters and re-space the hub motor to fit narrower dropouts. I just don’t know. But it is way beyond just buying a few parts and hoping for the best.

Good luck.
