Is attempting to Convert a C-20 to a K-20 even feasible?

[70-Shorty]

Just picked up this '71 C-20 longbed...got it for a grand. Has a 402/Turbo400/Dana 60 w/ 4:10's/factory air, current tags running driving truck. Previous owner brought it in to radiator shop for cooling system & AC overhaul. Ended up with new radiator, heater core, all hoses, misc AC parts and fresh AC charge (blows cold) and a new carburetor. Customer couldn't end up paying bill and they signed over clear title.

I would like to convert this to a 4x4 but the more i look at other 4x4s on here it looks to be quite a task. I've had lowered trucks all my life and been able to do most things (mechanical wise) or have connections to get it done if i can't, but i've never had a 4x4. Just kinda wanted something different as i have a lowered 70 Halfton shortbed already. My other thought was ditching the 4x4 idea and losing the 3/4 ton stuff and converting to 1/2 ton/trailing arms and shortening the frame and ending up with a big block fleetside shortbed with air Any thoughts? Foolish endeavor?
