I used a 1/2" drive flex ratchet to break the hard to reach nuts loose then switched to 3/8" air ratchet to finish. This is just what worked on a '99 u320

How long can the handle be on the flex ratchet?

Also, what are the prospects of removing the nuts on the bottom of the bag and using a sawzall to cut away the rubber bag up top, right next to it's metal mounting plate, removing the bag and attacking the bolts from underneath?

Tman,

The bolts are actually studs that are made into the mounting plate.  The route you are talking about would give you extra room for you to reach around and remove the hid nuts but you still have to be able to access the new bags studs to be able to tighten the nuts.

Short!
If you give the top nuts a shot of your favorite "liquid wrench," a day or so ahead or even an hour before, the top nuts come off pretty easily. I did it without removing anything (need small hands)  but with the Fiberglas out of the way, it's a still easier job. I put new stainless nuts and washers on. Air fitting was brass so just wire wheeled it. There are only a couple of nuts that are tough to get to as I remember. Was sort of a fun job.

Removal seems the hardest.  I had thought of a small hole saw to drill out the studs from the bottom with bag removed.

With coach raised on stands is it just a matter of capping the air line to the bag I'm replacing to keep the slide bladders
inflated?

You could do that or if your line numbers are the same as mine (might be since we both have 2003's) you can cap line 57 coming out of the aux compressor.  Then the aux comp can still provide air to the bladders.  This procedure will remove air supply from all airbags via the aux comp.  The airbags could still get air from the front and rear tank if you don't dump the air there too.
