Potentially they could look at making accessories being equipped by all classes/jobs again, but it's stats would vary depending on what equips it. So much like the Aetheryte Earring that adapts based on the job and level of the player, could do the same for accessories except it only effects stats based on job/role (and not level as well). This way you could have more glamour options for accessories, although I probably wouldn't want this for left-side gear even though it does feel there is a lot of duplicate stuff (in different shades out there...).
