An alternative, of course, is to give gear items two different "equippable by" lists, one for who can equip it directly, and one for who can equip it as glamour. That would take a bit of work to set up initially, since it would require a change to each existing piece of gear, but once set up, it wouldn't involve any increase in character data size or any of the other limitations that block them from so many things.
Either approach should be feasible.
