That's fine and all, but given nearly a century of rain bringing on turmoil I din't think any sort of broader institution as your suggestion would be able to just pick up and say, "We back to where we were before". This sounds like it would only really be a religious cult of the ruling class, since I doubt the lowly peasant with one change of clothes, no shoes, and who's probably living bare subsistence would feasibly care whether or not they're a god in a man's skin. And when the pressure builds over the course the deluge they'd likely turn on their worldly gods to get a few scraps of food, or protect whatever it is they can get, or over all the whole program becoming disconnected from one another socially or politically it'd naturally divide itself up: say someone somewhere, not knowing what's going on elsewhere declares themselves a Vicente Seventus Speritis, and begins the existence of an autonomous counter-office, and by post-deluge it's something of its own thing, because the people responsible have found out about the political and/or material power that gives them.

If you want to run a whole large-scale cult thing where everyone's a god that's fine. But I seriously doubt it would be as large as you're claiming it to be. Neither would when everything is over they up and decide to go back, other factors may have come into play that divided the land up, or seriously weaken it.
