Removing Torsion Bars? and leaving them out?

...the torsion bar is a great design. Just look up some articles on the "Green Brick" One of the benefits is that it is adjustable for some ride height and is easily replaced. Also non of the wweight o the spring is considered unsprung weight. But, if you insist on the air bag suspension, atleast build a correct mounting point. the upper shock mount is not designed to hold the weight of the car. Also do some reinforcing of the fron frame section [tubes etc]
DO NOT just put in a coil over shock type of spring [using an airbag of course] in place of the stock shock absorber and think this will work.
