Vampire's are pretty big right now and what better way to make sure the sequel ends up making us much money as the first movie. When Kirk isn't kicking ass on landing parties he sits in his darkly lit quarters wearing leather pants without a shirt on. He either is always angsting over the fact he is alone or reading Shaksphere to show the audience how deep and senstive he is despite his violent kick-assing he does on landing parties. If only he could meet a sexy but independent-minded teenager girl to give his life some meaning, which of course he does. 
Teen girls will show up in droves to watch the new Trek if they do this in the new movie. Also make Vulcans the mortal enemy of the vampires so Kirk might be betrayed by Spock only to be saved by younge teenage Carol Marcus.
