suspension set up question

[Ziegelsteinfaust]

I was stuck behind a expedition for 2 hours in a traffic jam, and I had me a idea.

Well the expedition is a big SUV with a hd IRS set up or at least hd for a 1/2 ton truck.

So what of a guy got the whole frame, and placed a classic truck on its frame. I am sure I would have to lengthen the frame for a rcsb wheel base.

Would this make a great handling stock height truck compared to a comparable solid axle? I am thinking air ride with a soft "spring" rate, stiffer shocks, and big sway bars.

Or even a 4x4 set would be pretty cray cray.
