There is a way to remove the cockpit entirely by modifying a livery file.
Actually it is not the livery file but the file in the airplane you want to use in its model folder and is named model.cfg
When you put ; in front of the exterior and interiour line on the bottom then there will be no cockpit
or airframe visible in the sim.
The only thing you see about your aircraft is whn you are in external view and it will be the airplane nav lights
