If so then a lift creating section on the front wing will be disputed just as the DF creating sections are. That way the affect of the sudden loss of DF in dirty air will be reduced by the the lift being reduced as well.
Also if you reduce rear DF the teams will have to reduce front DF otherwise the car will not be balanced.
I think this is part of the problem.
Currently, and in the past, Formula 1 cars are/have been terrible when following another car.
Say that all aerodynamic appendages stuck to the nose (wings, winglets, etc), lose 50% efficiency when in dirty air (yes, I'm making up numbers, but you get the point).
Say the 2008 wings made 200X downforce. The 2009 wings made 180X downforce (ends) and 30X lift (center section), totaling 150X downforce.
So in dirty air, the 2008 front wing made 100X downforce, and the 2009 wings made 75X downforce.
Now, while it's true that the 2009 front wing lost less ABSOLUTE downforce, at only 75X compared to the 100X ABSOLUTE the 2008 car lost.
However, they both lost a significant PERCENTAGE (50%) of downforce, and therefore have (herp derp simple physics) 50% less front grip.
And lets go with drag as well, assuming a 3:1 lift to drag raion, the 2008 had 60Y drag and the 2009 50Y drag (yes, this will be different, I know). So the 2008 lost 30Y drag and the 2009 lost 25Y drag.
Now, obviously I've simplified this to the extreme, but my point should be clear.
The issue is that the cars are still losing downforce a lot faster than they're shedding drag. A LOT faster. So what benefits to be had in a slipstream (loss of drag) are outweighed 3-to-1 by the loss of grip.
One solution, that means the cars lose much more drag than downforce is compulsory downforce at a low speed. If a car can maintain a significant level of downforce at lower speeds, then at high speeds it will make a lot of drag and the relative downforce gains drop off. That means, when in behind another car in dirty air, it will lose a lot of drag and very little downforce.
I imagine the way to regulate this is to show that flow underneath the main wing profile/s (front and rear) is attached at maybe 80km/h.
To compensate for the inevitable increase in drag, more powerful engines would be needed, something around the old V10's power would be fine.
