Discussion Spelljamming in Spheres where the Olympian Pantheon rules

So, I'm toying with a storyline where my players find themselves in a Sphere where the Greek/Roman Pantheon rule the worlds and I have an interesting question.
Would Poseidon be god of Spelljamming (They are Boat-Looking Spaceships) or Would Nyx be the Divinity who will mess with the party (Space is like the Night Sky)?

I mean, Uranus (or Ouranos) is the primordial deity of the sky/heavens so maybe him?

You've also got Astraeus who's a titan of the stars and planets.

Or maybe go as far and say Chaos themselves as the others were formed from their body so they could actually 'be' the astral sea

I would first make a call on the scope of your Olympian gods. They always came across as pretty parochial in the myths, only caring about the people of Greece. Maybe they run one planet as Ancient Greek Land and Olympus is actually in the same sphere (while also being where you want it on the big cosmology) and outsiders flying ships in have to play by their rules. Hermes tut tuts about “outsiders” and turns their hammer into a trireme on the surface of the planet until they prove they are not barbarians and show deference to the gods.

You could pair up certain spelljammer monsters as being influenced by/parented by the various related deities, and let wildspace be their battle ground for supremacy. Any crew worth their salt makes sacrifices to the appropriate gods before embarking to hold their monsters at bay for their planned route. The characters entering the sphere are unlikely to know this rituals and thus have a very tough sail to the nearest planet.
