How about we have it so you can see from a gun cam view when looking fowrward and as you move your head back, you can see the edges of the screen. This would simulate looking into the screen for the camera. And then we slave the head position inside the bomber when looking any direction but forward, that way, it looks like you're using a remote gun turret.
As long as it functions like a remote turret, and it looks like its a remote turret, then its a remote turret. No one is going to go into the servers and inspect to see if we really coaded a screen giving you a rearward view from the camera by the tail gun.
