That's definitely not all that common. I think just Frozen and Zootopia come to mind, which are admittedly the most recent two movies.
That said, this is an adventure movie, and so isn't set in the same kind of static backdrop that allows for a good guy to be the villain. She's going off with her pig and Maui on a journey. At best it'll be a short sort of turn over, like a classic fairy tale where someone offering them hospitality is really trying to eat them or something.
