good plan. It's about how I want to do it. I've been looking at putting a supercab with a bronco back end on a std. cab, long bed frame or a crew cab with super short bed on the same frame.

Supercab short bed wheel base is 6" longer than a standard cab, long bed so you just cut 6" outta the bed (which you probably know already). I have a pic of one I found on here somewhere.
