If we can have convincing SM+1 and even +0 "ships" we could be on our way to statting up missiles themselves as separate ships that we keep in a special hangar...

Damage and DR would need to switch from decade scale to normal, but that's not a big deal. More challenging would be the Control Room, for which the computer and sensors will continue to scale down, but the crew station will not. For very small craft a single crew or passenger seat will exceed 1 system slot. I suppose one way to handle this is to make a "Control System", which is basically a Control Room without the seat, and scales normally with the craft, then add stations as (pricier) Passenger Seats. An SM+4 Passenger Seat system carries a single occupant, so a single SM+3 seat would take up 3 slots, and an SM+2 one takes up half the craft. They could probably be made more compact, at the cost of comfort and life support. An SM+1 seat might even be external, making the vehicle a motorcycle or similar.
