Bane has the best/dumbest name thoough, which is just making him. Bane. From Batman.
Poseidon (Y'know, that Poseidon) was worshipped as a god of earthquakes, the ocean, and horses. That's before we even get to the Mycean approach which, we know little of due to Linear B being Linear B, but he started as an underworld god with no evidence of ocean links, but absolutely the earthquake and horse ones. You say clash, I say raises interesting things about the history of worship and how things have developed
The existence of "This is the God of Y, all the Y worship him" is a cop out already and unrealistic. It should be avoided as best as possible.
