I don't want to redo the whole installation because the outside is a
beautiful old fixture. What would happen if I glued the rod or shaft
(or whatever it's called) from the inside into the opposing thread?

I'm assuming you are describing an older door knob screwed onto a square
threaded shaft, with a set screw in the knob shank to keep it from
rotating on the shaft once it's been screwed down to its proper position.
That is correct, as far as I can tell w/ dismantling the whole thing.
I keep tightening the set screw, but it's increasingly useless to do
so.
More drastic measures are required.
If the female shaft threads in the knob are really stripped out, then
I'd suggest the proper repair would be to bore out the shaft hole in the
knob, soft solder a brass plug into that bore, drill and retap it to
suit the shaft and drill and retap the setscrew hole.
Failing that you might be able to use a helicoil to restore the knob's
inside threat, but the set screw hole could become problematical.
I'm afraid I am not competent to do either of the above
and can't afford to hire a qualified locksmith.
If you can't do any of the above, then take a shot at gluing the knob
onto the shaft. I'd recommend using "JB Weld" epoxy for that job.
That's what I was thinking of doing. But I posted on this NG to
ascertain
whether there is any downside to the procedure. Anything you or other
NG
members can think of?

Or. you could do what I did a six years ago when I had too much time on
my hands and decided I just had to trick out our home with a bunch of
antique brass doorknobs modified to fit its modern locksets, no two of
which now match:

Very pretty. But my outside fixture is more pretty g It really
is a beautiful antique, which is why I have been putting up
with this inconvenience for so long.
