I'd actually given this some thought, before Vincent sent me a spare Mk II cylinder. Looking at a bone-stock Mk I cylinder, it appears a trip through a lathe, turning off the threads would render a smooth cylinder shape. Followed up by hot-dip-brazing a proportional sleeve back on the formerly-threaded area would finally render a modified cylinder able to be fitted as-normally into a MK II receiver body.

A bit of fill-in TIG work on the un-needed extra gas relief holes would finish the conversion, with suitable clean up. A couple hours shop time, but still much less than turning and machining a new one.

If someone HAS the original Mk II cylinder DRAWINGS......I'd be happy to price out a new run of them.......
