True, but once turned into a soulless the Transformation spell will work. The Transformation spell is risky, but a pretender can always be called back by priests. Once transformed into another creature the pretender can cast Twiceborn and thus become the desired WightMage.

I wouldn't recommend this scenario unless you feel comfortable winning the game.
