If you were to make an X-Factor spin off of the X-Men film franchise who would you pick to play the following?

Unfortunately, X-Factor is not as iconic as X-Men. Therefore anyone would do in those characters, as long as they were similar in some small way. I personally thought Captain Picard (from ST:TNG, P. Stewart) was a perfect fit for Professor X as soon as I saw him, and Arnold would of been great for Colossis, and Molly Ringwald for Rouge (shows how long ago my thought was). I nevr saw anybody fitting the X-Factor cast as good.
