Her story with Magneto was wrapped, but I think it would be interesting to see 2 Mystiques, on opposite sides. Lawrence's version with Magneto, and Romijn's version back with Xavier (especially after Magneto dropping her as if it was nothing). I just simply think it would be a good way to address incredibly important relationships seen in FC with those that were seemingly non existent in the original trilogy to create one cohesive universe.
