Turned Taqueté - Four Block Profile into an 8 Shaft Draft

Turning a four block profile into an 8 shaft turned taqueté draft isn't as easy or straight forward as the two block, four shaft procedure.  First of all, when you turn a draft you are using the same number of shafts as treadles in the unturned draft.  With many four block profiles, your new turned draft will end up needed 12 or 16 shafts so you need to follow some restrictions in order to get a draft that you can weave on your eight shaft loom.

First of all, keeping your new draft to only 8 shafts only seems to work if your tie up is a 2/2 twill as in the profile below.   There may be other tie ups that work, but I  certainly didn't find any.

I made numerous attempts to do color changes in the warp and use a combination of straight threadings on eight shafts.  I could get a few to look OK, but they all had color lines that looked like errors, so I'm sticking with the plan I laid out above.
