Reading up on your first example, could Corsairs hire you to go away as well?
I know there's more to kill if you're inclined versus Corsairs, and I know having Merc is awesome because you don't have to limit to only one ZoI and things like that.
But if you're mainly there as enemies of Corsairs in Omegas, perhaps you could join one of Corsair's enemies?
We already have BHG, Core, MM, RHA, Smokeones and occasional ROS and whatnot. First three also fly around on contracts.
