I think what you need is a "bastard pack" lift. Meaning, you go to the junkyard and buy a pair of leaf springs. Usually from a small truck or SUV that has the same 2.5" wide leaves that we do on our YJ's. I would look for a pack that has multiple leaves, so you have more to choose from.
Then you take out a leaf from your junkyard pack, and replace a leaf or two in your YJ pack. Results may vary! But you can tailor your lift to what you want, and for relatively cheap. This is labor intensive though... and if you paid someone to do this the labor may exceed the cost of new springs depending on how much trial and error there is to reach your desired goal. Most people seem to use the longest springs and net about 3", but you could try the shorter springs and see if you get less lift. There are some spring charts on the web showing spring lengths and load capacity that may help guide you.
I am about to bastard pack my YJ, and picked up a set of leaves from an Explorer sport trac for $40. I hope to document my swap here when I do it, as most write ups involve S-10 leaves. I am shooting for 1.5-2" of lift. So I will be using the shorter springs from my donor packs.
There are threads here in this forum about bastard packs, just search and you will find them.
Another alternative is to have your leaves "re-arched". Most spring shops can do this, although I have heard mixed reviews about how long they last. I have no idea what the cost to re-arch is.
