Thanks for that, I hadn't considered the forward view. I was just thinking in terms of the rotor aerodynamics wrt vortex ring entry conditions. Tilting the rotors and tilting the whole plane would appear to achieve the same object - changing what could be considered a nice, flat, forward moving disc into one that is 'sinking' into its own downwash.
Obviously, you can haul the nose up a lot further than 5 degrees, but if you're on the edge of VR anyway (asymmetric or otherwise) tilting the nacelles or the nose is going to drop you right in it (literally and figuratively) isn't it ?
By the way, thanks for the wishes, but I think I'll be at the back of a very long queue for that one.
