Dual Rear Axles?

I have this thought pondering around in my head about a "Recovery Team Vehicle"

I have a 95' Chevrolet K1500 and an 89' K1500, I am thinking about taking the rear end from the 89' and installing it in the 95'. I am thinking of moving the rear end in the 95' forward to make room for the second rear end. My question is how would I power the furthest rear axle? I was thinking of somehow installing a second transfer case behind the first transfer case backwards? Will a transfer case run and operate correctly if it was installed backwards?

So to clear up some of that jabbering: My thought is to install a second rear axle and a second transfer case backwards behind the oem transfer case. The oem transfer case would power the front differential and the second transfer case, then the second transfer case would power both rear axles. So I would still be able to power the vehicle with just one rear differential with both transfer cases unlocked.

The first axle is a kind of straght through design on 6x4 trucks. It goes in the front and out the back then to the 2nd axle. Heres a diagram, a simple one at that. Do some research on 6x4 trucks.

I don't want to power all 4 rear wheels at the same time though, maybe I will have to just spend some time in the garage pondering this with all the parts in place.

i think i understand what you are saying about the transfer cases.

and i think you could make it work, but something might have to be reverse rotation to get everything spinning the right way.

the problem is getting the driveshaft to the second rearend because the first rearend will be in the way.

Why not just make a duallie instead. You can get nice kits for this.

I don't want a dually, I want dual rear axles if I do anything at all.

My thought on the second transfer case was to have it so the "front driveshaft" part of the transfer case would be vertical to go over top of the first rear end and attach to the second rear end.
