The premise works -- there's a plausible motive as well as an MO (that of creating multiple backups; perhaps your rogue/fallen 'god' for lack of a better term has been fought and destroyed by the pantheon one or several times before and is therefore presumed dead, giving them the advantage of surprise if they entered into a new form and then just hibernated and/or made preparations for centuries whilst waiting for an opportune time to try again).

Interestingly MarshalSolgrieve has the idea for a janitor on the crew to have become deified as Hades, with the humans having some sort of burial ritual that results in the corpses actually being taken down pipes or tubes to a physical underworld where they can be processed, for "sanitation purposes". So this state of things might be at least in part to deprive your character from being able to quickly and quietly amass an army of the dead if they return again, and similarly, the other gods might view uploading and/or backing up their minds as taboo due to its association with your character.

So yeah, the existence of that underworld is a nice coincidental thing that keeps the threat level of your character from being too great. There would naturally be some corpses available since not everyone or thing would receive the proper burial for various reasons, but it means there aren't graveyards with tens of thousands of corpses waiting to be converted into soldiers. Perhaps you should discuss some things with solgrieve because I see the potential for some significant overlap there. As an aside, I've been wondering why you use the > markers to greentext.
