It would be cool if professors and administrators from Discover University could show up as NPCs at school, but I won't get my hopes up. Knowing this game, it's much more likely that we'll see Eliza Pancakes and the usual gang of unemployed sims show up as teachers and in other positions once the premade staff has died or become played sims.
Also, I wonder how the pack will handle teenage celebrities if you also have Get Famous installed. Will teachers interrupt their own lessons to marvel at the star student in their classroom? I can definitely see it happen... (although I really, really hope not.)
