What I was referring to was more of an idea that if say a complete set is stored in the commode, it could be consolidated into one commode slot. The set item would still function the same as if the the pieces were taking up slots individually. The player would still be able to glamour the pieces individually. The set itself would just take up one slot, instead of 5-10 slots (depending on the size of the set).

I suppose if a set could be removed from the commode, it can be turned back into individual pieces in the same manner as the set box items that they've introduced in Stormblood. Consolidating sets into one items would basically be the same function, except in reverse.
