I would love that. I used it a lot in Dragon Age 2, to give my lady Hawkes the right hair for every occasion. Something nice and fancy for the Dukes invitation, something easy to do and maybe a bit more messy for adventuring...
I like the idea of being able to customize my characters for every situation.
Literally did the same thing in dragon age inquisition!!!

almost in every other quest I changed my lil elfs hair to suit the occasion
