Kevin,
I guess I would be concerned about clearance. Even if you beef up the springs via airbags or whatever, short of making it physically impossible to compress the springs, you still have the possiblility of hitting those tires.

I remember I used some spacers that fit between the coils on the front coils on an old '65 Buick Wildcat. The springs had sagged from age. While that did raise up the front end, the local auto club diagnostic center noted that the use of these spacers would reduce the travel of the coil springs thus transmitting more shock to the frame and body of the car. Sort of the equivalent of bottoming out the suspension.
