I'm not sure if what you're requesting would be something that can be done easily. If I were to take a shot in the dark I would assume you would need to play with the AI's, though don't quote me on it. One thing I am sure of is that you can't do what you're suggesting by editing the hardpoints - those only define the ships properties (strength, speed, weaponry, etc.). The hardpoint does tell the ship what AI to use (unless a mission dictates otherwise), but it doesn't tell that AI to behave a certain way (target priorities, combat effectiveness, etc.).
