"What if you have a flat, now, or even worse with the setup to which you
plan to switch?  Most of us wouldn't want to have to remove the drive
shaft and be without 4WD capability."

I agree with having 5 in-rotation. But, I also have a tire puncture repair
"kit" and pump to deal with" ordinary" flats. I haven't had to put it into
service YET (that ought to put it into service!). Unless I have a more
serious puncture or sidewall slash-type failure, I can see the benefit of
just being able to repair the tire without removing it/changing tires
enroute.

Just so you know there are alternatives until you can get a 5th wheel, which
is recommended with Syncro's.
