I've done 1" steel pipe in the wall before.. it busted the seam on the pipe, but that was because it was 100yrs old and rusty.

Home Depot rents the tool. I bet if you called them, they would give you exact measurements of its radius.
I have no Home Depot's that rent in my state. I can just buy a threader on Amazon if I decide to go that route. Not sure yet

That compression coupling will work But I wouldnt use it. I mewntioned threading it as well.
I think you are spinning your wheels , maybe you have a reason to not just make that hole bigger and gettr done. unscrew the riser or remove the valve and riser together

I would suspect that you have an old big hardware store that threads pipe.

Is your 1/2 inch brass pipe 0.840 inch OD? I think that would be close enough to solder a 3/4 inch copper fitting to. 3/4 inch copper pipe is 0.875 inch ID. I expect solder could make up the difference.

I got it all done today. Total pain in the ass and I had to open up a small section of the above wall with diamond lathe, plywood and more wood underneath, but I got it done. The new valve works great and everything is working again. Thanks for all the help!

There was no hesitancy to follow advice. I was getting ideas from the advice on different ways to approach it. At first I tried to cut the brass nipple to slide a piece of 1/2" copper pipe inside to sweat a new male adapter onto it, but for some reason the 1/2" pipe wouldn't fit the inner diameter of the brass nipple. So then I had no choice but to open the wall at the shower elbow and run pex down to the valve. I was hoping to avoid it, but at least I didn't need to tear open the whole wall.

It was very very close to fitting inside the nipple. There was probably years of build up that shrunk the wall ID a bit and I decided to just move on. As usual I couldn't have done any of it without the help from this forum. Thanks very much everyone.
