Modding crew requirements?

Is it possible to decouple the skeleton crew requirement from the maximum crew requirement, with a mod? I'm poking at some minor things (like it taking 2 clicks per crate of supplies to buy food on the surface), and it would be nice if I could mod WE ARE CLAY to reduce the skeleton crew threshold (because they help run the ship) but not the maximum crew (because they don't need quarters, they can take up hold space instead). I know it isn't easy to do, but is it possible?
