Oh man, I saw 8 last week and had so many ideas for the ship, that thing was huge, so many rooms. Would fit perfectly to the game and gives you a more vertical experience.
I'm hoping we get the boat from Part 8 and maybe the space ship from Part 10. I'm not sure how those maps would work with the normal mechanics of the game though (like calling the cops, for example)
Calling cops can stay calling cops, maybe they come via helicopter or you have to go to a specific location where they "dock on" and you have to go there.
Escaping can even stay too, you just have to repair the life boat.
