FLD 132XL Conversion Possibilities

I've been looking to purchase an FLD132 XL as a project truck. There aren't a lot out there in my price range and most of them aren't configured the way I'd like anyhow. (Cat engine with an 18spd transmission) I currently own a '96 fld120 SBA(set back axle) and was wondering if anybody knows if a truck like it could possibly be converted to an FLD132 XL. Specifically, would I be able to move the front axle forward on an SBA frame? Obviously I would be getting a new hood and the panels behind the wheels if it were possible as well as air cleaners etc. I realize there would be other things that would also have to be addressed, but in the end, if a SBA could be used for this build it would open up so many more trucks that I could consider purchasing for this build. Alternatively, could I use an FLD120 Classic and move the cab rearward to compensate for the longer hood? Might be opening a can of worms considering this I know.
