I think the reason the Givi screen works is it kind of wedges the air and speeds it up.
You maybe able to achieve something similar with that screen if you play around with it.
You could then have the screen lower but still have the air travel over the top. ??
I love it when people think outside the box, nobody wants to pay for a Givi but there is no doubt they work.

Out of my depth in a puddle.
Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
