Upgrading Expansion Equipment

Since they already have been adding relic equipment to magians, why not add the final armor pieces from A Crystalline Prophecy, A Moogle Kupo d'Etat, and A Shantotto Ascension Missions? Maybe have an options to make the base stats stronger, the stats you can choose enhanced by doing trials for them, and or maybe a final trial to add an additional augment?

Why not all expansion rewards like Raja's, and the earrings? Maybe give people that haven't bothered with those missions more reason to do them and the people that have them to upgrade them. They seem to have a knack for rehashing old content so I don't see why this could not be possible. Don't think it would take to long to implement either.

i believe they said at one point they were looking into CoP ring upgrades however they never got back to us with a final yes or barance answer.
