I mean if he seriously came back, ever, that would kinda defeat the whole point of P3 and its heavy emphasis on moving on. So yeah, if its ever going to happen it'd kinda have to be a joke for a goofy spin-off, like PQ or the dancing games
Ah that makes sense, but what I was thinking is that this was a what if situation where Atlus really wanted money so they revived Door-kun, what would be the best way of him returning without ruining mostly everything
An alternate universe maybe? If they really want to bring him back I can only think of a situation where he doesn't sacrifice himself thus leading to another outcome, that doesn't destroys P3 pourpouse and it's more of a "what if".
