Edit: I suppose I could put the old Super Maxy back in, but would that directly relate to the Super Mighty?

I believe I now know what I need; 68mm shell, 125mm+ spindle, English thread, ISO taper. I'm out of my wheelhouse here, but I've searched pretty well and can't find anything worth using with those specs.
