I don't see pirates being able to disrupt an enemy Mooring Ring as a downside, no more than a Policeman disabling a Tradelane to stop a smuggler.
The Mooring Rings would need to be made neutral, yes, to stop us getting ourselves blown up.
I believe it is possible, I've tried a few things myself to get it working, but I believe it involves Hard Point modding, which I am unfamiliar with.
If I ever get round to it, I plan to do a test where I replace the mooring ring arch type with a tradelane arch type, and see if it works that way.
And yes, I was only refering to the Mooring Ring, and not the docking ring. Most smugglers only use the mooring ring, as they fly large class vessels. Smugglers in fighter class vessels will still be able to get around it yeah, but lets face it, its' possible to blow those up in a short amount of time.
Although, this won't solve all of the oorp smuggling problems. I've chased software smugglers, only to have them dock at west point. But it isn't practicle to disable a stations' docking systems, in both aspects of the game and in RP. It may cause problems for people trying to launch.
