The bigger issue for me is talking about "gods" "living" in the "intermundia".
I don't recall that we've discussed this but it would probably be interesting to pin down exactly what it was about being "between the worlds" that the Epicureans would have associated with the idea that this was a particularly hospitable place.
I suspect we today would look for the reasoning revolving around gravity or the spinning of galaxies or the atoms being more "spread out" with more space between them or something like that, because we would think about all the matter in a particular area being attracted toward a localized center. But I am not sure why that would translate in Epicurus' mind as an environment easier to sustain oneself in. Fewer atomic collisions?
I don't expect we would take the same approach at all today but if we understood what he was thinking about we'd probably have a better understanding of whether the gods are "by nature" imperishable or whether they "act to maintain" their imperishability, and that in turn might make the entire picture more relatable.
