So... for it to do what you want, adding air needs to make the car sit lower. How do you do this? Well, maybe by using the airbag to compress the coil-over spring. Then you could set it for max ride height with little or no air pressure, and lowest ride height with max air pressure. Unfortunately I have yet to dream up a configuration that will do that.

There's a company doing a "smart" air ride setup now that you can lego together. You set the heights. Basically uses a TPS sensor at each corner. Based on the deflection it adds or subtracts air pressure real time via solenoid to add pressure on the compressed side. (Stiffening the spring rate while maintaining height) and does the opposite on the inside. In theory it should handle rather flat.
Works with a generic bag over shock system to retrofit coilovers.
I don't necessarily trust it yet, largely the sensors. (There are really nice shock travel sensors for drag cars that would be much more confidence inspiring.)
But compared to an air bag in a cup over a coil over it may be the best compromise. (Been eyeing a Fortune 500 setup for a car. Same rates and dampening, just a 1.5" lift for curbs.)
These guys are testing it on a diesel swapped 240z. (Om606).

No affiliation with either, but seems like a score given how easily a locost builder could adapt any cheap local coilovers to air with a set of calipers and some time.
