Firestone sells two different bag mounting systems that may accommodate what you want to do:
1. The first type is bolted to outboard side of the frame rail and sits over the leaf spring's U-bolts.

I assume you would plumb the two left bags to each other and the two right bags to each other to equalize pressure. You could plumb each bag individually for redundancy in case of failure, but it would require more work to manually equalize pressure and not have one bag doing most of the work for the two.
