[Harry Potter] If a dementor took Harry's soul, leaving Voldemort's 1/8th soul, would that soul take over Harry's body?

No.  The soul fragments left inside horcruxes aren't really meant to be self sufficient.  Voldemort did all sorts of extra magic on the Diary to make it what it was.  The question is whether a Dementor would even be able to do the kiss on him, and if it could there's a question of whether anything would stop them from sucking everything out at once.  Note that Nagini still had to be killed with the Sword rather than regularly.
