Here is a pic of the front driver's tire up on a ramp with the angle of a stock rear ds to a 8.8. Only thing added to the stock rear ds is the flange to bolt to the 8.8 pinion flange.

However, from what I understand to be the question, I would suggest you look into a local 4wd club and find a reputable member that welds there. They usually have experience and can help you decide which route to take for the Jeep and your terrain you will be driving as well as outline availability and expense. Also, they will work for cheap compared to a reputable weld shop. Understand that liability will be on you and not the welder, thus talk to many members as you can to locate the better welder reputation.
