This is an interesting idea. While I personally enjoy being able to see at a glance what people are actually wearing, and I've enjoyed watching the colour scheme of Lower Jeuno change over the past two years as AF3 and Abyssea gear came into the picture, I wouldn't necessarily be averse to this sort of thing. (Especially if, in the process, it removed the 'blinking' effect from a character gear swapping mid-fight; an in-system solution to the blinking problem would be phenomenal.)
