It's awfully cumbersome to work with just the biggest size filter for everything. I personally have round glass filter sets in all the sizes you list because I never carry all my lenses at the same time, and lighter weight and portability is often a priority. You might want to think of two sets : 82mm with a 72mm step ring, and 67mm with a 52mm step ring. If only three filters are involved, it's not going to be terribly expensive to get a smaller second set, plus you'd have a spare if something gets damaged - and sooner or later they will.
