Yep. Been thinking and planning on doing the same thing. Cut the knuckles in a similar manner as you would do a cut-n-turn on an axle, pull the knuckles completely off, flop over the axle, put the knuckles back on opposite sides than they came off and weld them back up after you've set your angles. Cut out the welded diff cover and rotate 180 degrees, notch any new notches necessary for ring gear or diff-lock fork for the diff to fit back in the tube right side up, ensure proper diff stud location and make any necessary changes, and flip the drain plug to the new bottom side as well as the breather tube to the new top (filling in the old holes of course). Weld up your suspension and shock mounts etc, and bob's yer uncle. A bit of work that should be done by a very competent individual/shop, but I've seen it done on both front and rear axles. Makes it nice to keep it all Yota IMO.
