At least on the '98 E-SuperDuty, the rear leaf springs are by design rather flat rather than obviously elliptical like most leaf springs are. I don't know if the E350 is similar or not, but it's entirely possible that the springs aren't supposed to be vastly different even when the rear end isn't sagging.
I have Ride-Rite air helpers and they seem to work very nicely indeed.
If you have a competent truck chassis and spring shop nearby, it may be worth your time and money to get their opinion on the matter. I can suggest one in Essex Junction, Vermont and another one in Whitehorse, Yukon that I've had good experiences at, but that's probably not very helpful.
