It's an interesting idea, but it runs counter to the way Final Fantasy games are made nowadays (offline). However, I can imagine some kind of active world part of the game, where you can create a character, or for a strictly multiplayer sense. It's hard to say. People show the FF I thing but Final Fantasy hasn't been like that since the SNES days. It will be interesting to see how this new system gets implemented in future games, however. Realistically, though, I wouldn't have a problem if they did try to do some 'back to the roots' thing with XVI and make a character creator for the main party or main character.
