Does make sense.

But are you sure, that you don't want memory? It is only one small step away. Besides drivers seat will drain power even when it is not used and car is locked, if consumer cutoff is not used. No switched power source is powerful enough for seat motors. You could use a relay, but you will be switching up to 30 amps. Plus more switches, buttons, stalks (electric steering column) is better + mirror tilting when reversing.
