I really don't think this will happen, for several reasons.

- There are already several mages that use Water Magic. Aquarius (well she's gone but still), Juvia, Partly Mira, Cana and Lucy (if she can still use Star Dress Aquarius)

- Wendy was originally supposed to be a Water Dragon Slayer, but that idea was scraped and was replaced with Wind.
