Not strictly, Legendary Armory related, but more related to ascended Armour and templates, can arenanet somehow make Ascended Armour stat unlockable, e.g you have a piece of ascended Armour but you can 'add' stats to it and thus once that stat combination is added you are able to swap the stats between the various added stat's sets this would make ascended Armour slightly more usable with build templates. Instead of currently needing either multiple sets of Armour, and or reforging the ascended Armour in the forge just to change it's stats.
