That make it a whole different situation. New question, Why doesn't he own a road bike? Does he at least have a second wheel set for his superfly? That might actually be all he needs. If I am correct, the Superflys are carbon and actually pretty light for a MTB. He could probably get some thin 700's with disc mounts and some 25-28 slick tires and be doing just as good as a new bike at a quarter of the cost.
