Well, you could make the leather sheath in the same style as a fold-over kydex, i.e. leave off any belt-loop and flare eyelets at strategic positions along the seam, thereby allowing for attachments that increase the variety of carry-styles - left/right-side as well as scout/high-ride/low-ride/dangler etc. If you make a sheath like that, I have a universal kydex extension you might like to try.
