Have xz as an option for what ?
As others have already pointed out, rsync works with files on filesystems - it does not work with files embedded in other files. In the same way, it doesn't work with a disk partition and work out what files are held within the filesystem on that partition - you are expected to mount that filesystem so rsync can access the files. It would be incredibly wasteful (understanding filesystems construction) to duplicate that functionality into rsync !
I'd concur with others - if there's something like a fuse module to mount the compressed archive as a (read-only) fileystem then use that, otherwise you'll need to re-assess the whole process.
