Not really as a god, but I’m willing to believe it’s Zoro, since his journey in Wano has been so parallel to Luffy’s throughout the entirety of the arc. Even in just Onigashima the two of them have been in multiple similar scenarios
Den_Den_Mushi made a great post about it being him too:

Otherwise maybe Momo, his name ends with 月, as does almost all the other major clans in Wano, but he’s individually more important so it could be him
