OP why not develop the way to change the Glamour system to do what you want? It is pretty hard to imagine a way to save the Glamour to a saved set when you Glamour an item. The only way at present to do this is to have two of the same item and Glamour them as you want for the different set.
This isn't really possible, not even the Transmogrify system in WoW can do anything like this.
