I am an ATCO, & not a pilot. You have the advantage of me there ! However,based on my experience, I would have thought that ATC everywhere would have only made things much more difficult for itself if it tried to rearrange traffic out of an existing or natural sequence & into a more artificial one. I DO KNOW that this would have been the result if I had tried to do such a thing, I would have been making a rod for my own back. I canīt believe that this would be any different in Europe; unless it was a very quiet unit.
However, as I said, you have the advantage of me there !
If so, I bow to your experience.
