There is always a problem when people or cultures try to equate a god of one pantheon with a god from another; there are too many differences. Odin may be king of the Norse gods, but in many ways he is different than Zeus. For example: Zeus is associated with the thunderbolt. The god closest to Zeus in this regard would be Thor; not Odin.I think there is more to it than simply adopting Greek gods and renaming them. I believe many of the Greek and Roman gods were descended from an earlier Indo-European root, separated for a time and then reconnected. For example, while Zeus and Jupiter seem to be quite different names they are actually from the same root: Djevs. Which became "Zeus" for the Greeks "piter" I believe is the same as "pater" or father. This leaves only the "Ju" part of Jupiter and I think you can see how Zeus-Pater or Father Zeus could easily be related to each other. The Romans recognized the similarity between their own and the Greek gods. They believed that many gods and godesses of people they met must be the same gods that they themselves worshipped. I always thought it interesting that the Romans equated Odin with Mercury rather than Zeus. Does anyone know why?
