I'd rather see GEO as a caster, since adding it as a healer would give it too much overlap with WHM. WHM may not have those elemental spells anymore but SE didn't get rid of them completely and you still have them when you sync down. GEO would utilize them in different ways but having two healers fulfill essentially the same aesthetic up to a point wouldn't feel very creative. It would be much more interesting to see those elemental spells pushed into a more damage focused direction and be a mirror of SMN and SCH; two jobs that fulfill the same aesthetic (summoning) but use it in opposite ways.

IMO Chemist is the one that makes the most sense to add as a healer seeing as how it would be completely unique compared to the 3 we have now. The team focus on the idea of class fantasy and they might want to capitalize on those that want on a more mundane healing style that relies on technology instead of magic; we already have 3 casters in the role and having a fourth would feel stale. AFAIK it's also the last job they could add to the role that was explicitly a healer in previous games.
