I think you should move Julian out; you appear to have the least attachment to him than to any other of the characters mentioned. And I can hardly handle one smug in my town, I can't imagine having more than one... they're emotionally exhausting, lol.
I would say Julian as well since you didn't mention him in particular as to liking him or not. If you feel as if you will have too many smugs after getting Marshal swap one out for him. ^^
