You could be a binary clone of Angel and Colossus, and get a combination of their powers.  Once you're already creating clones, combining two sets of DNA into one isn't that big of a deal.

I'm not sure I'd allow it for two powerful people, but those two powers aren't super powerful on their own.

Maybe the super strength could be part of it too, but to a lesser degree.  Full Colossus plus wings might be a bit much.
