Elias isn’t the type of person who’s greedy enough to become a god. In my opinion, he would rather die as a human. Reincarnation is possible as seen with Amphitrite and her lover, so the gods would (im)patiently wait for Elias to reincarnate and chase after him all over again.
But not all of his lovers aren’t morally good and would probably force him to become a god, so that’s also a possibility.
