Not sure why you'd feel that way. That's how several real-world polytheistic religions worked.No. And Thinking about "analogues" for what are fundamentally completely different deities is an element of Crawfordism-Perkinsism that I hope we leave behind.
Ishtar (Mesopotamian) begat Astarte (Phoenician). Astarte begat Aphrodite (Greek). And then Aphrodite was syncretized with Venus (Roman). Likewise, Hermes is probably an offshoot from Pan (as in, formerly an epithet of Pan, Pan Hermes, "Pan of the piled stones"), and Pan was an offshot of an un-spellable Proto-Indo-European deity who also spawned a Vedic pastoral deity, Pushan. Hell, even within a single religion it's quite possible to have highly divergent takes. Poseidon was originally the head of the pantheon, back in the Mycenaean days, when chthonic gods were much more prominent--which made all the myths about Zeus's ridiculous antics a lot easier to explain. Further, certain gods could be worshipped differently in different places or at different times. Zeus was Zeus Panhellenos, "Zeus of All Greeks", but he was also Zeus Xenia, "Zeus of Strangers", as he was the god of hospitality.
A relatively clean solution to the problem of having literally hundreds of gods is to instead have a relatively constrained pantheon--say, forty-ish, counting deities of all alignments--and then different cultures perceive and worship some deity or set of deities differently.
