definitely more places they could go with that, both literally and figuratively. Different eras, different places, etc. It's still hard to follow-up a series where it was literally a battle between God, gods, God's immediate family, etc.

But it would still be like making a spinoff from Buffy/Angel about the Watchers. Fascinating in theory, but they could at best be fighting low-to-mid level threats, which after the Buffy/Angel series, would just not have the same stakes.
