Yes, I'm sure that would work. The only thing is, though, that there
might be a dead spot in the middle, so if you're depending on the
motor to cause its own reversal, you might need to incorporation some
mechanical hysteresis.

AFAIK they will work to replace wires, but that application seems unproductive.
