Let's see... generally, people are of the opinion that the ships above Gunship-class are for use in the Bounty Hunters' war against the Order, not for actual day-to-day bounty hunting, as they're too expensive to maintain for such comparatively trivial work. I'm inclined to agree. Remember that in addition to the pilot, they also have a crew to pay, and considerably more complex weapon systems and other such things.
I'd prefer more limitations on Codename weaponry, but the refusal to allow Nomad guns is good to see.
It appears that you're only targeting player factions, not independents associated with the NPC factions. Is that the case, or are you also going to target, for example, independent Corsairs?
As for shadowjman: There's a Bounty Hunters Guild in Freelancer, even without the Discovery mod. I would think, therefore, that they're considerably more organized than you seem to think...
