I don't understand. Docked weapons are turrets. Whether they rotate or not. What exactly is it you are asking for?
I think he means allowing direct control of a docked entity's weapons, while being in the main ship. You'd basically just "inherit weapons" and then they'd show up on the weapons screen, shooting in the direction of the weapon orientation, and aimable by the user.
If I am right, then I like this idea, because it would help balance the way power works for turrets vs main ship weapons. Currently, I believe it is too limited what sort of power per second can be devoted to a main weapon compared to turrets.
Though I think I should add that anything considered a "Turret" should not be controllable through inherited docking, because it wouldn't work right. Though a separate way to quick switch to turrets might be good.
