that chunk is not that big as you might think and can easily substituted by making her either Inhuman or Eternal or whatever in heritage. No, fanboys won't like that change (at first) but it doesn't really change anything about the character itself, just gives other explanations for her powers. Is the Magneto angle needed? Not really. That came late in the game. SW worked well for decades before she became retconned into Magnetos daughter.
And MS would 'gain' another female Avenger that was one of the earliest team members and one of the longest team members in Avengers history...before Bendis messed her up
