I would never want to make that repair, have it successfully pass proof and then 10 years later and X number of round later it lets go and takes off a hand.

I love the idea of pushing the limits and trying it. Do it, prove it passes some form of proofing, feel good that you could do it. Then sleeve it anyway. Save the tubes or send them to someone that keep them and demonstrate what can be done.

I would not want that weld on my conscience for all the future holds. You never know where that gun might end up, who might shoot it and what they put in it.
