Well the wabbajack is an on target effect from a staff so you are changing someone else into something. I think he was getting more at Polymorph Self kind of effect so you change. So not really "sort of" You already have lycanthrope to turn into a werewolf so I don't know how difficult it would be.
And as the OP stated most people play on console so midas magic is a useless suggestion for them.
