Yes, but don't they make one for a 22.2mm quill also?
So if one could massage one of these modern hangers into a more organic shape, and devoid of all anodize, it might even look good and would solve the OP's problem in a simple way.
But perhaps not as simple as just milling down the threaded race and using Loctite?
