I think it's feasible. Heck I would think that conjury could prolong life also, in theory.Â
It would have to be a pretty rare talent though, so it would rely on a kind of esoteric wisdom rather than being a no-brainer of conventional astromancy. You would need to be able to explain how it was that your character came to possess this special knowledge because it would certainly be a coveted talent if you have the secret to prolonged lifespan. Bearing all of these things in mind, I think the only foreseeable issue with it is the extent to which it makes your character "special," which might bother some people.
I doubt the lore will explicitly touch on this kind of thing but you should wait to make sure it's not explicitly contradicted. Other than that I'd say go for it, as long as you give it a realistic amount of weight and bear in mind how specialized it is.
As for waiting for Heavensward, that might be advisable since I am sure the job quests and guildmaster dialogue will shed a lot of light on Astromancy.
