Out of those Neville or Justin. I overall think it should be someone with little to no drama going on so I would naturally go for a Ravenclaw or Hufflepuff.

@Asnootforsnoots wouldn't it make more sense for Minerva to be headmistress? I mean she was already second in command and followed up Snape. I think he just got the job because of his connection to Voldy

If Voldy wouldn't have returned... Dumbledore didn't had to go for hunting of Horcruxes and he would still be alive...So why the change of headmasters??
