I wasn't sure about Mishin because he's openly said he doesn't like training ladies. Plus, he seems pretty concentrated on Plushchenko right now. Maybe Grutter (she wouldn't need to move far). Hill is a long shot. Maybe Raphael Arutunian? Or maybe Kurt Browning? Or does he just do choreo?
Mishin complained about Russian female skaters not being competitive enough before.
But I think now he might have a different idea on that since he's training very talented young Russian girls for 2014 Olympics.
