Id put some steel shims in there and call it a day.
I think I have 4degree shims on my sprung under FJ 40. I have a 4inch BDS spring lift and 2 inch over stock shackles. Clearing 35s without issue.
The Cardon joints will help out and the shims will get the pumpkin pointed toward the Tcase.
The only reason I would cut and turn an axle is to go spring over with stock leafs.
Again this is for an FJ 40 but a CJ 5 is close for size/weight. Spring over with stock leafs will get you about 5 inches, depending on the sag of the springs.
