I have zero answers to your question but have another question for you. If the rear of the truck is leaf springs and you were thinking about converting the front to leafs to make it a four wheel drive, why does it matter in the rear whether the frame is a little different as long as it is already leafs? Cant you install lifted springs or blocks just like you would do on a come from the factory 4x4? To me the tough part would be converting the front of the frame to leafs (no skills lol). Maybe the mounting pads are located differently? Seems like an easy fix for someone with your skill set.
