I think you'll find a problem when you cut the small hole in the race upper fairing - the design proportions won't be correct: too much bodywork for so small an opening. I think MV is the only bike who has handled this detail properly so far.
I'm not sure what you mean here... do you mean that it will be difficult to cut the hole in the fairing, or that it won't look good appearance-wise because of shape of the fairing?
I realize that a single round headlight in the middle won't appeal to everyone, but i personally don't like the look of the factory headlight. I tried several placement options using photoshop (twin side-by-side, single offset to one side or the other, etc.) and the single light in the middle appealed to me the most. I'd love to run without a headlight at all for the sake of appearance, but that's obviously not legal.
