This seems a rather silly thing to try and poke at.
In a (very rare) defilade-type position you describe, the larger and lower spinning rotor of a conventional helicopter causes essentially the same occlusion within a couple of degrees, but over the entire circular arc instead of just the narrow aspect wing area. This difference is accentuated due to fact that the gun positions are largely forward of the wings.
The dual engine and pylon arrangement and the tiltrotor platform has proven itself in combat with the V-22 for going on 15 years now, from both small and heavy arms fire. Just look up Rooster 73 in south Sudan, or the DFC awards for the Osprey pilots flying in Afghanistan in 2012.
