Mod request - remove head limits in gunner positions

[Mulbin]

I'm playing FC in VR, so having an invisible forcefield preventing my looking over the side when in gunner positions is a real realism killer. I can switch it off in the pilots seat by enabling spectators, but it has no effect on gunner positions. Is it possible to make a mod that kills this awful feature?

For some background on those not familiar with WW1 gunnery, "observers" weren't strapped into their seats, they were attached to longer tethers to allow them to lean, stand, crouch...and in some cases even climb half out of their cockpit! Being artificially stuck in a bubble is not realistic and only makes sense with WW2 aircraft.
