Yes you can adjust the height to some degree by removing leafs, generally starting with the overload. However, you may find that after pulling the overload leaf the spring packs start to invert where it meets the axle which can break leafs over time.
Here's an example from Zach's build:
The 02-04 trucks have 2 leafs plus an overload so you can't pull any leaf BUT the overload... You might be able to get away with pulling the third leaf from an 00-01 pack (they had 3 leafs plus overload) but you would only marginally lower the rear as the 00-01 had thinner leafs than 02-04 (something like 1/4" -3/8" going from memory).
The overload leaf in my Eagle packs was really thick (~0.75") so I pulled it but then my leafs started looking like the picture above. I called up the spring shop where I got the packs and they cut me some custom helper springs that will support the middle of the pack much better but aren't as long, or as thick as the overloads (the helper springs are also curved to match the arch of the pack).
Also keep in mind that with the stock setup, the axle side of the rear shocks bolt to a pin welded to the U-bolt plate. If you're going SOA, you're probably going to flip the U-bolts up out of the way at the same time which will move the shock mount way higher than it's stock location. You'll have weld shock tabs to the axle tubes in roughly the same location to get the shocks mounted properly. I highly recommend double-shear shock mounts... I've seen single-shear mounts rip off before.
Here's what my setup looks like (this was before I pulled the overload leaf):
