Diversity for the sake of it is best exemplified by Captain Planet, or pretty much any eighties cartoon or sitcom with a conscience.
Kirk would have been easiest only insofar as he's one of only three characters that are given any kind of sexual identity in the movie, but, again, it would have been out of character when Pine's Kirk, in most ways, was just like Shatner's.
As this was an action movie, and I expect the rest of the movies to play the same way, making someone one of the supporting characters GLBTQA is pretty easy, and doesn't even require any dialogue or missed time. Simply have him roll out of the bunk he's sharing with another guy when the ship goes to red alert or is otherwise attacked and you have what you're looking for without changing a core personality trait of a character.
