While my feelings on the subject are largely academic, as I've no real intention of reading it anyway, Dick being in the Titans right now would just be... weird.
Batman should not be in the Teen Titans, even if they've dropped the "Teen" off of it.
Sometimes people have to outgrow certain things, whether they want to or not. While he certainly doesn't have to outgrow the friendships, I really think that if they're going to give this Dick-as-Batman thing a shot (though who knows if it'll wind up just being "filler", as it likely will), maybe it's time for him to outgrow the concept of eternally returning to the big T-shaped tower and grow into what we know he can do, head up to the big... something-shaped... moon complex... thing.
