well, I would say it would be a fun time getting the spring pack back together again and then you are running the main leaf in a configuration that is opposite to what it was made to do. personally, i wouldn't but i'm sure there is gonna be somebody who says go for it. they are new springs so at least you have that going for you as far as compared to using old springs which would likely crack after a few bends the "wrong way". they are arced for use the other way so using them backwards would be counter-intuitive because they would be simulating carrying a fair load just sitting on the ground installed upside down in the pack.
remember the main leaf, if cracked, is gonna give you a real ride because it is what orients the axle in the truck. any of the other leafs are just "going with the flow" and will cause a sag but not catastrophe if broken.
