Geoff I would not even attempt to stand it up with the heavy glass. It barely did the 400. I think the 200-400 would be a big issue which it also fits. I would say that is a fail in the design. Just as a hood not to bad. Another note you need two hands to put it on and take it off.
I used a 4th Generation Designs Canon 500F4 lens which I had surplus, I purchased some longer screws and 3d Printed a spacer which allowed me to reverse the hood.
Sorry can’t attach a photo, PM me if you want to have a look.
