I am very interested in what a F1 that makes more of the downforce from the underbody, and is designed to generate less upwash behind it and be less sensitive to turbulent in-flow would look like. I think you would want to have a longer downforce generating floor (so the low pressure acts over a larger area and makes more downforce), with less rake on it (for less upwash to be sent to the car behind?).
Look at the "bargeboard" area on this Ligier/Spectrum S5000 car... It's a much more simple and cost-effective design than what F1 uses. It takes the clean air from under the nose and sends it under the floor, and neatly spits out the dirty air from the front tyres to the sides, without being made of 1,000 pieces like the F1 version.

The front wing, was almost certainly, developed in a much more economical way than a F1 front wing too...
