With the 'return to driver' feature of some of them, I could see it being technically possible without much fuss. I think logistically it faces some challenges. This would be somewhat prohibitive on where the stations can be located - each spot now needs to more or less afford two. Things like ensuring the vehicles trying to get out of the way don't settle up/park in the entrance path.
