People use all sorts of weird stuff to put an edge on a razor, I can't really see a power strop as practical, unless you are going to install a bench grinder in your bathroom and change out one of the wheels for the strop. Or go crazy and put 3 bench grinders in there and have 6 power strops with different pastes on each.
You could even cut your hones into discs and mount them on bench grinders too, about 3 additional grinders should do it.
Then you could install a couple of turn tables to save on space and mount 3 grinders onto each one.
OR you could just use a hanging strop and a couple of stones :)
