Glamouring two separate headpieces together?

[ElHeggunte]

I think they need to do away with the clunky glamour system and just give us glamour slots in the first place that we can drag-n-drop gear onto. Or at the very least, let the glamour prisms save the appearance to a slot instead of the equipment and have the slots be saved per class so that you could, for example, share one piece of gear between several classes and still have it look different for them all without having to manually change it every time. A good example would be putting all of your crafters into the lvl60 Adept's set, but whenever you switch to a specific class the gear immediately takes on the appearance of their lvl50 class gear with no more work on your part besides having already "pre-set" the appearance of the slots earlier.

... I can dream, right?

Edit: I just realized that I never addressed the OP. Adding another vanity slot or two specifically for the head like Felis suggested would alleviate that. I can't imagine other vanity slots working very well though. Only other slot I can think of that would make sense would be the back, but things like capes and wings would just wind up being a clipping nightmare so no thank you.

Edit edit: After thinking about it for a few minutes I realize that glamouring the slots would just make you take on a specific appearance no matter what you put on, which may not be desirable. This is why we think our ideas through before sharing them, kids! Of course maybe that could be alleviated by having "slot sets" like how we have gear sets. So you could still have several appearances saved per class.
