Turn Full Gear Sets Into Coffers

Im fairly new to the game and im not sure if this is even going to go anywhere but I had thought pass through my head and figured MAYBE just maybe if i suggested it they might add it to the game. What would everyone thing about being able to turn complete gear sets into a coffer to save space in your inventory? For example if you have the FULL set of Ironwork gear for MCH and you out grow it you can then turn it into a coffer and save it for when you start leveling your BRD up and you can open the coffer up and use the gear again so it is all in one place. I personally have a few gear sets but they are scattered in different retainers chocobo saddles and such it would be cool to have it all in one slot in the inventory when needed. What do you guys think?
