Again, I'm also not aware of any screw-in tank regulator that is externally adjustable up to or over 1000 psi output. I also have serious doubts that Luke or XMT would even want to tackle such a project, what with all the liability involved.
A question, however, is why you would need a screw-in type regulator to be externally adjustable? Don't like the RONCO way of doing things? (Set it, and forget it!)
