honestly, I have no idea if that'd work. I never even made side characters in my cycling towns so I wouldn't know, however, I'm not sure if you'd get that same notification from Isabelle on a day someone's moving out. ya know that whole "so and so is moving tomorrow, as mayor it might be good to go say goodbye". since you wouldn't be playing on your mayor, I'm not sure if she'd even notify that character at all. that doesn't necessarily mean no one will move, but I'm really not sure how it would play out. worth a shot though! :') let me know how it goes if you do decide to do it.
