I've seen lowered 4x4s before, but they've all had the IFS. You really need to look at everything that could potentially come in contact with the axle and/or frame; I.e. steering, crossmembers, driveshaft, exhaust, oil pan, etc...you could be looking to do something that just isn't practical for a solid front axle truck. I'm sure it's possible, but it's probably not a good idea.
