Dolphins, Orcas and Belugas should not have military slots, they should have a couple of dedicated passenger only slots. Type 6's, 7's and 9's should not have either, they are focused on logistics and cargo and therefore would be much better suited for that role than the Cutter. I should not be allowed to take a Vulture and make it just as good for cargo than a Hauler. Because that implies that the Vulture was not built from the ground up to be combat focused. That means smaller hardpoints to make room for non-combat roles, smaller distributor to make room for other roles, smaller thrusters. You have to make room somewhere for extra optional internals, you can't just put some space magic in to put more optional internals in a ship where there is no logical room for them
