Ooooh... elaborate please. I'm a big jam band fan but someone like Trey didn't occur to me in this context. Maybe the parameters of this thread aren't super well-defined but insofar as the topic is, while sitting in the keyboard seat, which guitar player do you want on stage with you, I'm not sure any of the jamband heavyweights -- Trey, Jerry Garcia, etc., would be my first choice. As an audience member, I definitely love these guys but -- controversial take(?) -- as a keyboard player I'm not so sure they are at the top of my list compared to other guitarists named in this thread. It may be that guitar styles in other genres appeal to me as more complementary to the keys.
