I can definitely see him as Hank, but I hope that whatever incarnation of the character we get, they at least build up to him being blue in some way. If nothing else, it'll save the internet community from having to hear "wait, how is he white if he's blue in X3?", like with Sabretooth's portrayal in X-Men Origins, as opposed to what we saw later. Just build towards bridging that gap and all should be fine.
