Meant to reply to this ages ago.
Not really interested in revisitng the spacesuit - a simple image repeated 50 times would do for a generic spacesuit ani - if you can't see the head at all, there's nothing to animate. If anyone needs one, a quick PCS2 shot and a little bit of post processing to get rid of the face would do it. Besides, BP uses a different suit to that ani (See the stuff over his right shoulder? all lost in the BP model), so for them at least they'd need a new one anyway.
FYI, if I were to do it, I'd probably put the suit in Max, light it from three different angles, and render that, possibl with subtle changs in the lghting over time. That way, you can either have some limited diversity from one character, or you can have three visually different spacesuits talking to each other without needing to animate three separate heads.
