I don't imagine the whole 'these guys are in a big fleet' aspect would capture his fancy for too long, he'd probably be more interested in an unaffiliated aspect of the universe, maybe working class space guys, folks trying to get by without near-infinite magic box tech or big guns on a mighty ship. I know I

Essentially, I think he'd be more interested in BLAKE'S SEVEN than TREK in any of its incarnations.
