mog station needs

[Kirito]

There's an entire line of minions only available through the mogstation. So stuff like that already exists.

Well I am not sure if minions can be associated with a player's personal expression in the same way that hair styles do. And the minions available are only the ones that resemble the main characters (except for one, which was a part of a seasonal quest). I am not sure if, lore-wise, it makes sense for you to get them in game.
