The CGI de-aging worked well enough in X3, but I reckon it'd work better with actual make-up. I'd greatly hope for him to return as Xavier in the Magneto origins film, as long as Sir Ian is still playing the elder Magneto. Of course the younger versions of those characters would have to be played by younger actors, but for their mature incarnations I'd love to see the 'original' actors.
