I don't know, we bought our L94 with 6L80 for only $5000. It came off of a wrecked 2011 Denali with only 11,000 miles on it. At the time, Moby was already running PR60's front and rear and so the only real cost above and beyond that was the Motech kit and labor. Depending on where you're at with your Jeep now and how much you can do yourself, getting into an LS isn't as unreachable as many seem to think.
But, let's just say for argument sake it'd take $25k to get you into an LS, $5k is 1/5th of the way there! And, from the dyno results I've seen from superchargers on JK's over the years, most only get about 25HP at the tires and off road, all at the wrong times. Again, that's why I chose to be patient, save up a bit longer and get something that would deliver REAL performance. But, that's just me.
