They wouldn't really have to rewrite AST lore at all. They'd just need to point out that CNJs are actually GEOs through a filter/intermediary. Which would mean that AST and CNJ are related disciplines as well...though that isn't really too outrageous and doesn't change either's existing lore, it's just a twist on how to think about it.

I COULD see Time Mage as a healer (reversing wounds, etc), but I can't imagine they'd make it one, given Time Mage has always been a damage/buffer in past games where it has existed. Though I think it also has had the Regen spell in some games, too...but in FFXIV, WHM already does, so unless they plan on WHM changes to Medica 2 and Regen, I can't really see it happening, and FFXIV is allergic to hybrids, hence the RDM situation.
