If nothing else, this would also fix the armoire issue. My retainer is currently holding my 2014 moogle suit, and my 2016 tidus and yuna outfits, that is 14 slots filled by glamour gear that cannot be armoired or bought from the CS, if I drop it, I lose it forever. However, if I could add it to the glamour log, I don't have to keep it anymore, and I feel like they could even release gear as exclusively "glamour packs", i.e. instead of getting lvl 1 tidus gear, you get a Tidus glamour book that would add the set to your glamour log.
