Surely it would be easier to turn fine multi start left & righthand threads on the taper ?The pressure on the knurling tool would change as you moved along the taper which would change the appearance anyway, probably able to show that the knurls coincided or not though.
Edit: Turn the taper with an off set tail stock, that would sort out the pressure change with a push knurl but not a scissor knurl.
