I'm thinking of adapting a Sinar Auto Shutter to use IN FRONT of the front standard, for barrel lenses in the following way: there is a Sinar adapter the shutter attaches to (from a gentleman in Hong Kong) and the other side of the adapter fits like a lens board on the front standard. The screw-in opening on the shutter front will take a Technica type adapter(screw on one side, regular clips on other to hold lens mounted on Technika boards). See:

My questions: seems like this should work? The gentleman is also working on a Sinar 5.5" adapter - this would be better than the Technika, since it would allow for bigger diameter barrel lenses to be mounted than on the Technika board, no?
This seems like a better arrangement than between standard and bellows since it is more portable and less disruptive of camera, albeit requiring a modest investment in 2 adapters.
Auxiliary questions re the Sinar Auto Shutter:
Is there a controlable aperture on this shutter or are those f stop numbers on the side display a reading when a lens is coupled to the shutter? Why is there a screw in hole on the shutter front? What was it (the threaded hole) originally for? Is the intended use for this shutter to go between front standard and bellows? Then I guess this could work too with barrel lenses mounted on Sinar boards and no protruding rear elements placed directly in the usual way onto the front standard?
Sorry if this is a bit unclear; it reflects my unfamiliarity and confusion regarding this type of shutter.
Thank you for your help!
