Hi STimpy,
Please check out the photo for comparison to the original police one in the middle.
With my brackets you will notice that the top portion is longer, it extends further forward, by approx 45 mm and the holder for the spotlights is approx 10 mm higher than the police issue.
I have done this so as to get extra clearance as would be needed for a larger style after market screen , and or larger diameter lights.
My model for a screen is a V stream , and also a Bike Quip screen which measure approx the same across the wide part of the base as the OEM but the profile is different and moves in relation to the spotlights on the bikes that have the electric adjust .
I could do a special custom job but I would need a true model to base it on and I have never seen the wind deflectors that you mention.
In my opinion lifting the lights an additional 100mm would not be practical , too much windage causing undue vibration, and would look quite unsightly.
