A button push kill with a macro attached : "Zu Li, do the thing!!" that works in raids

In all seriousness now, I'd love to have a "temporal glamour" item. Think of it as a temporary phantasia : you can save a unique character appearance on it (only once, like a phantasia) and then use it eternally as a glamour (if I may say). I'd really like to swap my looks with my alt's every so often, buuuuut not for a long time and I can't really afford the amount of phantasias I'd need for that.
