Can you widen a 14 bolt sf?

My cousin has a Suburban rolling chassis he likely will give me after his dad, and him use it to fix their Suburban. Plus convert to to 4x4 at the same time.

It looks to have everything I want in a project base from the pics I have sent. Which namely is a 3/4 ton, and the 14 bolt sf.

My last square body 14 bolt sf was 2" per side to narrow to match the front axle, and this being a 4x4 is probably 1" per side to narrow. Part of my project is to have the rear wheels out to the edge of the sheet metal, and then fronts tucked in a bit. So I can have full travel, and a lower ride height for bombing dirt roads, and or rally cross events. Which is a future goal.

So has anyone widened a rear axle? Is there a limit to what a sf axle width should be?

Also what are the longest leaf springs that I can purchase used? Preferably 3" wide. The gmt400 has 63", but 2.5 inches wide. Any other maybe better options?
