I recall reading an article in one of the gun rags decades ago about a guy who had some barrels made. He had a rare / odd old autoloader with a bad barrel. Feeling flush, he went to a machinist to have one made. (Apparently, this guy really knew how to properly make gun barrels, it wasn't just a pipe that would fit!)
Anyways, it turned out that the machinist told him that once he was set up to make one, it would not cost all that much more to make a hundred. So the writer took him up on it and that was the purpose of the article --- to see if anyone wanted one of these barrels at a reasonable price.
Now I'm not saying the article was accurate, and I'm just going from memory. But it has made me wonder if some individual or group wanted to front the money, how hard would it be to find a company that would make barrels for the S&W M1917? Obviously, if they cost $2,000 each, that would be prohibitive. My guess is that S&W would not be interested but it may be worth a discussion about who could do this. Just a thought.
