I have a simple solution that would ALSO save on serverside storage. If the armoire would hold one of each item, then the items you put in it don't have to have their own instance , they are destroyed and added to the list. Items in your armoire should be accessible by the glamour list. They would only have to track items by name in your armoire and not look for an instanced version of the item in your inventory. Now this also means that you lose the dye and materia on the items .. but as some that NEEDS more space and loves glamouring I'd accept that.
