Any image you could share to illustrate this feature? I'm not sure I understand correctly.
I do not have any of pictures personally, as every game to have it, I didn't play, or didn't add the feature till after I quit. (WoW being one of them.)

If you have a WoW account, I'd say check it out, if not, maybe jump on a free 10 day trial.
(not sure if you can do it at low Lv.)

EDIT: I take it back, I did play Aion, which had it, but you originally had to be Lv30 to do it, and I stopped playing at Lv28 or 29. (Woulda loved to mix some armors together I really liked.)
