I don’t know if they relased the skins by their names yet, but Pharah could be just a reference to Cerberus. And JQ as Zeus seems more like they are interpreting her personality as Zeus-like.
I can see young 76 being a Zeus type of character, but present Soldier is closer to Hades than to Zeus. I’m making this analisis thinking more about the personas of the gods, but I don’t think they went that far thinking about this.
