Putting the frontier back into the Spinward Marches

To me, the Spinward Marches doesn't feel much like a frontier area.

I am thinking of modifying the worlds a bit. A quick way of doing this would be to lower the population number by one, the TL by one (with a max of TL 13), and lowering the Law Level by one.

I'm thinking that this would make the area feel more like Firefly.

Does anybody have any thoughts? Would it do what I want or not?
