Yes, you could experiment - but I do not consider it a serious problem. I replace most of my hoods with round metal ones and then just cap the hood.

That sounds like the best solution. I haven't looked into this in awhile, but just did a trip thru Europe with my son, his first time. Lost my hood in Paris in the Metro. It just vibrated off! Anyway, the round metal, hopefully screw on, might be the best. Have to test the vignetting. I get this once in awhile shooting in 18mm even with the Nikon hood.
