Well, straight-up magic IS a thing in the Dragon Ball universe, so she could potentially pick up some interesting new abilities.
I GUESS that Roshi could introduce her to Baba, but Baba’s never really seemed like the kind of person who would have the patience to teach magic. Though learning that Sunset is a Unicorn would probably interest her, if only to inquire about the differences between magic on Earth and in Equestria.
Maybe Kami? While Popo is training the Z-Fighters, Kami could do something? I don’t know.
