For the people suggesting cutting and soldering or brazing.
There is NO WAY to get at the spot to do ANY OF THAT without taking out
walls and conduits.
That's why I'm trying to find ALTERNATIVE SOLUTIONS.

Can you touch it? If so, it can be cut and soldered. Not everyone can do
it, but a good plumber can. Pre-tinning it can even be done with one hand.

Another saddle valve may be an alternative, other alternatives are running
a section of PEX, butt that depends on what is accessible.
