That said, if you're going to explain away Scarlet Witch's powers as actual magic, it's just as easy to rewrite Quicksilver into a completely different person to explain him - make him an Inhuman.
That's a pretty off-the-wall origin change....but I like it. I could see him fitting in quite nicely as an Inhuman. Of course, incest would rear its ugly head again (kinda follows him around, doesn't it....?) if you still want him to hook up with Crystal.
