There's really no point in doing that. A dana 30 with alloy shafts is pretty close to being as strong as a Dana 44 in all the important ways.
Except housing strength. Then the D44 adds greater aftermarket support and better prices for diffs, gearing, highsteer, etc.
I run 5.38, had to go to a Waggy D44 front and Isuzu D44 rear. Good thing is 4whl discs and matching 6-lug all the way around.
I run 35" radials on the street and 36" TSL's offroad, this thing is more driveable than when stock. Cruises along nicely in 5th, can even accelerate up moderate grades in 5th. Passing, no problem.
I don't think you'll be happy rowing the gears with a heavy truck tranny, I'd regear the axles low to compensate for the tires and your jeep will be a lot more driveable.
