Glamour space seems to be a consistent problem in FFXIV and the main impediment to implementing it, as stated by Yoshi-P, seems to be server space. I was curious how much thought was given for low to no memory glamour solutions? In particular solutions that use already existing database tables to cover some of the need for a "transmog" like system.

For instance, the market board and crafting logs contain tons of equipment that characters can try on, and are already stored on the servers. Rather than have separate storage for each players, have the server query the table that stores either the market board equipment or the crafting log tables, and allow players to apply those items to their glamor plates similar to how the armoire can be used.

As far as the question of what equipment characters are authorized to access, you could have each character store a list of the equipment they've spiritbonded with at some point. However, the problem with this would be each character could have potentially hundreds of entries to indicate everything they've encountered, which may or may not be too much data for the system.

Another solution would be similar to hunting and crafting books that players unlock. Have level/job range books, probably crafted by alchemists or sold by merchants, that players read once, and that unlocks a range of items they can see, similar to how difference jobs and levels can be filtered when using the marketboard.

I acknowledge there are intricacies in the code that I am not familiar with and cannot claim there won't be problems with this solution, but I am curious if using data from either the marketboard or the crafting logs as sources for glamour plates would be viable? It would definitely reduce a lot of space in the glamour chests, which characters could dedicate to dungeon gear or other untradeable gear.
