Tell me if I am crazy, or at least any possible problems

This is what I want to do:
Take a 1972 c10 that was my grandpa's and a late model chevy 4x4 and make them one.
I would like to take a wrecked newer IFS and install it on the c10 frame or cut both frames and put them together somewhere in the middle. Install the new truck rear end in the factory trailing arm suspension. My idea is that I will have the better ride of the springs and the convenience of FWD when I need it. (this will not be a rock crawler or a mudder, but a street daily driver) Use the 5.3 or if lucky a 6.0, the transmission and transfer case from the newer truck, fabricate the crossmembers needed, and have drive shafts made for the length I will need. I would like to install the portion of the firewall that has all the heater and air conditioning hoses blower motor from the new into the 72. Shave the heater controls from the 72 and install the controls from the new truck. Even modify the gauge cluster from the new and install into the 72. Mount up the computer and run all the wiring from the new. I am thinking that since I will have almost everything from the new, the computer will not need modded. I plan on using the master cylinder from the new as well so the only thing that it would not have is the air bags. Once I get that all put together (I know it is going to take a lot of: measure, measure, cut, check fit, tack weld, check fit, break weld, cut, check fit, tack, measure, check fit, weld) then it is going to be, shave the rain gutter, shave the fuel tank fill, shave the antenna, replace rockers, cab corners, door skins, and parts of the bed. Then body work and paint. This will probably take 10 years.

So what do you think, am I crazy?
