Well, you see, you might want to bump issues, if you think they're deserving of work. Maybe some coder will pick them up; you never know. I can, however, pretty much guarantee that you're going to see even greater weirdness with the solution you're trying to do (As a test, try shooting at those turrets).
You see, LOD0 is used by the engine as the collision mesh for any collisions; if its geometry is vastly different from the rest of the ship, gameplay will be affected.
In the end, Dragon's solution of integrating the cockpit mesh into the fighter and using that as LOD0 (with the cockpit mesh placed in a detail box) will probably work best for you.
