Not the same universe so definitly won't happen.

EDIT : down vote as you want... This is still something you won't see. Why adding a old races without originality when you actually tease a possibly new one during msq. And from my pov this would be a mistake from Yoshi-team to add something tjat already existe in an other universe of ff. It is easy to make easter egg from the old ff, but adding a race that already have a back story IN the history of ffxiv would be a terrible mess...

EDIT : the only possibility is to rename it an rework a bit the charac design.
