I like this idea as well as the using this idea for weapons.. I'm tired of the whole clone wars at the end-game I see in other MMOs. Even WoW now has a system where you can make your high-end gear look like any other gear your class can equip.

For those saying that is what materia is for, you are wrong. The only way materia can replace this system is if U/U gear can have materia added to it.
