I mean, the ghost would have to have some kind of science-fantasy explanation that's only marginally more believable than ghosts, like it's some kind of psychic projection or something. But even that does seem like A Lot to add to this already very A Lot-ish concept.

Because then it is a giant space ship with a spaceport, cult terraformers, a ghost and a giant gravity influencing insect.

And that would definitely take things from A Lot all the way to Too Much, for sure!
