No, you won't get that behaviour with AI goals. Don't do it.
You can get that behaviour, in a precisely controllable fashion, reproducible every time you run the mission, by constraining capships to flying waypoints, arranged in whatever flight path you want them to fly. You cannot get this behaviour delegating capship control to AI, which is absolutely horrible for capital ships, as it essentially makes them behave like giant, mentally-retarded fighters.
Besides - You can't give capships "avoid ship" orders anyway (I don't think that order even exists). It won't work even if it did.
It's also needlessly complex and stupid to do that when you could just tell them to follow the ****ing waypoints, which can be set into however complex a flight path as you want (given the capship is able to physically perform the maneuvers with its turn time/radius).
