It will be fine if it is just adding another identity to her.
But Marvel Studios likes to simplify things so if she ends up being a mutant, it's unlikely for her to get her mystical elements adapted, meaning no Agatha, Chthon, Modred, etc, those who actually serve as her supporting characters rather the other way around.
And while it may be beneficial for her to appear in X movies, I don't want her wide spread wrong impression stronger than it already is.
Worst case scenario is her ending up in brotherhood for some drama.
