the basics will work, like cowl and doors, the problem will be in matching up the roof - if you examine each you'll see the crown of the panel is much different than a pu - you'd hafta cut the cab off above the windshield and mate the complete roof of the panel right there at the 'brow', including the top of the door openings - be quite a job making it all fit, and I'd think the available patch panels for yer bad places would be easier
let us know if ya try
