Personally, I dislike the idea of multiple "Soul Societies", it just feels weird to me? Though, Soul Society didn't have to always be Japanese. Curiously, Kubo's timeline basically ends in the early BC. But Human civilization? Much longer than that. History of the world? Yeah, definitely much longer. Soul Society could have "reformated" time and again, as the Quincy made clear during the invasion its not exactly hard.

I do like the demons idea for Hollows, though. I've been toying with similar stuff in the past (Spiritually aware Human sees a Shinigami performing their duty, spreads the word, rumour becomes myth and so on).
