A workaround comes to mind.
MD5/SHA1 (whatever) the files and hardlink them under that name into a
(hidden) directory.
Then when you rsync with "-H" those hardlinks (All files must be below
the start-directory) make sure that rsync only has to delete/create
hardlinks and not copy them again after it had copied it the first time.
I use a similar method for a bunch of big files i have, i hardlink them
into a hidden directory and when i move the files around rsync only
deletes/creates hardlinks. When i move the files onto other storage i
only need to do "find .z -type f -links 1" to find out which files only
have 1 link. Which means all other hardlinks are gone and i can remove
that file. ("find .z -type f -links 1 -delete")

Real Programmers consider "what you see is what you get" to be just as
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated,
cryptic, powerful, unforgiving, dangerous.
