My three leading candidates are the Contax No. 5 (67mm), the Pentax RA-67, and a Nikon HN-23 (72mm, with a 67-to-72 step-up ring). A seller has told me that the HN-23 is 3 inches deep, >> HN23 is a 62mm thread, actually - we are out of them now but 3" seems about right. It is doubtful that you would suffer vignetting with with a 10mm step down. Also that hood is about the most common & therefore least expensive of those you mentioned. When I had my 135mm F2.3 S1 all those years ago, I found the b/in sliding hood grossly inadequate, and picked up a 90-180 Flat Field hood (keeping it strictly Vivitar, you understand) - most delightful.
