so if you swapped cells and found that you had to rack the standard backwards or forwards by 46mm to refocus infinity then I think anyone woud expect a problem with the aperture scales being incorrect
Sorry... wrong.
As I said above (#6), Flange Focal Length (FFL) has absolutely nothing to do with the aperture scale.
That's because the FFL has nothing to do with the optical focal length. The f/setting depends on optical FL.

If you believe you can, or you believe you can't... you're right.
