He could try to take over Barry's body to kill Ralph to blame him for a murder. Well, it's already been pretty much established that Devoe specifically wants the powers of the bus metas. He could've taken Barry's body at the prison but didn't for an unknown reason. Barry himself pointed out that the whole "frame Barry for murder and get him sent to prison"-thing was nothing more than an elaborate distraction in order to keep Team Flash busy.

Whatever Devoe is planning, I don't think that taking over Barry's body is part of it.
