Tacoma Chinook

Hello, I recently have been looking for a custom camper shell for my 2001 tacoma 4x4 so far I am not finding what I want. then I had seen a 77' Toyota Chinook for sale & it gave me an idea and sure enough! I found you on this blog. My question for you is, is it possible or to take the Chinook cab and put it on a 2001 single cab 4x4 Tacoma? or would there be just to many mods? thanks for your input.
