Yup.
I think the system would need to be automated to fully unleash the potential.
It shouldn't be too difficult to do based on the difference in deflection between front and rear suspensions.
Front suspension compression less than rear* = more front downforce
Front suspension compression more than rear* = less front downforce
Obviously, it will need a function to describe a variance as the rear has softer springs than front.
Also, the system would need to consider braking & acceleration.
But its not too many variables. Certainly compared to an engine map it can be approximated much simpler.
