Some simplistic ideas:

Limited venturi tunnels under the car - they worked well in CART when tightly regulated so should be fine in F1. It's not really a case of porducing less turbulence, the venturis tend to re-laminarise the flow and thus are more efficient at producing downforce when closely following a car.

Banning of any aerodynamic devices on the upper body of the car above the horizontal plane of the wheelnuts between the vertical planes of the rear of the front wheel and the front of the rear wheel, including aerodynamic suspension parts. Cooling chimneys also banned, as this would force bigger radiators to be used, hence more drag and a larger tow for following cars.

Slick tyres - no brainer really.

What I was getting at seems to be the asame as you, the shift of emphasis on downforce production from the upper bodywork, which seems to be far more sensative to changes in the air stream (like turbulance from the car infront) to the floor which seems to be less sensitive.
