Modified Step-side Bed

I have a '67 Chevy C-10 that I just bought not too long ago. I am planning on making it a street truck with a 50's hotrod kind of feel. Flat black, wide whites, Von Dutch style pin striping, that kind of thing. My question is this. Do you think it feesable to take a short bed fleetside, narrow to the width of a stepside, then mold in stepside wheel-wells so that I'd end up with the old school look of a stepside, but retain the body contours of the fleetside. I think it would look great, and be pretty simple to do, but if anyone has any imput it would be apprechiated, I have loved the hobby since I can remember, but this is my first project (I got sick of drving around in the family Taurus!).

Here's an idea for ya'. The '88-98 Silverados had a bed already shaped as you describe called a Sportside. The center box portion is steel, the outter side panels are fiberglass. And you won't have to fight getting the tail gate narrowed, which would probably be the toughest part of the job. If you search the yards you can probably find one fairly reasonable, and they fit the earlier chassis. This is the best picture I could find, it's a little chopped off the back, but you should get the idea.

Bob - yea, i've though about that, but i kinda wanted to stick with the classic body lines. I think the new beds are a little too smooth for the 67-72 Chevy cab and front sheet metal.
