Idea?

[ghettocruiser]

I've got an idea for a new project. I've got an 82 cab and shortbed that came off of my first ever vehicle, that I of course wreaked. The frame is seriously tweaked as well as the entire front clip, but the cab and bed are almost perfect. There is also an old longbed farm truck that belongs to a friends of mines dad that I think I get for real cheap, if not free.
What I've got in mind is to shorten the longbed frame and use the front clip off the farm truck. I want to restore it with all new electronics, weatherstripping, and other wearable pieces to make it pretty much a new truck. With the interior and exterior completely stock with exception of wheels(20s?) and maybe bags or just a static drop. And powered by a new series motor(4.8, 5.3, or 6.0).
Does this sound like a good and reasonable plan? I want to do it as cheap as possible but not just hack it together. Also, has anyone used the vintage air system for these trucks or would it be cheaper(easier) to go back with a stock system?
