Good thing about the leaf springs is they disperse the weight of the body to 4 points on the frame. Then if you have coil over helper shocks like I do then you have 6 points of load distribution.

Then if you go to a singe leaf spring you are putting a double point load where there is no existing vehicle frame.
So any weight saving just got added back by having to use a heaver single leaf spring and from adding an additional frame cross member.
