At one point, maybe. Remender made Archangel a bit too badass though. I don't see how Swift can dish out enough damage. Warren was slapping the shit out of X-force and was generally looking herald-ish. He never fought mainstream Marvel outside of the X-Folks, but his daughter was going toe-to-toe with Thor. I just got the impression Warren would have performed similarly or better.
Don't see Swift winning regardless.
