Cab frame length questions

I can't get this crazy idea out of my head of a 12-15 V6 6Speed Access cab body on a regular cab frame with a short bed sitting on FJ cruiser full time AWD running gear. It would be like a Toyota Tacoma WRX and I don't even know if it's possible but I want it so bad.

Would an AC cab and a SB box fit on a SC frame? Where SC frames ever made 6 lug?

 

Yes they did make a 6 lug regular cab not sure if it would hold the access cab an or not though.

 

Anything can be made to work, but as far as it being a literal drop in fit I dont think we're so lucky. The difference in wheelbase between RC and AC is 17.8 inches. The difference between longbed (6 ft) and shortbed is 13.2 inches so I'd think there'd have to be some cutting involved to make that work.

I'd be content with a simple 4.0/6-speed/TRD supercharger swap into my RC.
