Can I suggest that if you go with the LS Version, that you could optionally increase the Resource drain based on the amount of occupants in the gravity designated hull?
I have my own Gravity Drive that I use for flying my ship,
I have it so it has increased power consumption based on constrained entities, and it serves 2 purposes.
1. Its really realistic - more bigger ships = more power to lift.
2. it makes it harder to build bigger ships, which in turn limits the size of laggy ships to medium size.
