Somewhat along the lines of what I have been thinking lately, although the FCs are not big enough for this, yet.
The Idea is the next level: SuperCarriers == FCs on steroids, if you will. Not for the timid. Not for the Poor. Carry fighters, and System Defense type ships == Anacondas, Vipers, Eagles, the whole mix. Can be hired out in a system, i.e. there are missions to provide system security. With the current limits of how many players can be in an instance, and if the defenses regenerate instantly like the NPCs that jump you on missions, attacking one of these babies would be a very dicey proposition, especially if they were on a mission that specified that their repairs would be paid for, (and you would have no way to know if they had acquired such a mission, so even a very successful attack could be for naught...)
One of the ways this might be made to work, and give some people a real challenge to bang their heads against for a while. Might be less bunny bashing if you can keep enough of them busy enough long enough...
