The Egyptian Pantheon had Heliopolis on the second level of Arcadia, which became its own plane in 3e FR (Mesopotamian Gods have Ziggaruxus which has made a appear in 5e,it's being pulled out our of moth balls after the return of Untherite Gods, were it goes is anyone's guess, I'd personally put it on the 3rd level of Aborea) Personally I'd make Heliopolis the 3rd layer of Arcadia.
Also it's often Forgotten l, but Limbo had Layers named after Hindu Gods Indra and Rudra, and a Japanese Goddess.
Mechanus is also call Nirvana.
Other Gods were more scattered.
And honestly the Greco-Roman, Egyptian and to a lesser extent Norse Pantheons shaped Western civilization so far much more then Eastern or sub-Saharan African ones, so it makes sense they'd have used those more, both because they are safer and because of greater familiarity. As immigration increases that is likely to change.
