I know most people would think it's stupid and crazy, and I can't disagree on that
It'll probably never happen (at least by me) since there are a lot of other projects that are way ahead as far as priorities go.
That said, I can't get the idea totally out of my mind. It would be cool to try and marry up a bunch of Jeep Grand Cherokee driveline pieces (shortened chassis), with a GTS body style, and do a crazy 'road warrior' type of paint job on it. When I do that rough calcs, things 'look' like it would be possible to get everything to fit (with a ton of work). Problem with the JGC is that the body is an integral part of the chassis - so it's not as easy as just lifting the JGC body and popping a GTS body on it. There would be a ton of frame work to do to keep the thing from breaking in half or twisting itself to pieces...
When I was in high-school, a guy down the street from me did a job on a Stingray that was so ridiculous it was cool. I think he took a lifted K-5 Blazer chassis, built the heck out of the driveline, put a 427 in it, and got the Stingray body to cleanly integrate (with a roll cage). It was beyond ridiculous looking, but when that guy took it offroad and really ran it hard, it was a sight to behold (and a sound that blew your mind). That thing was the quintessential apocalyptic road-warrior vehicle.
