It sounds like you might be interested in Unison:

Another option would be to rsync with a hard-link copy.  This way you'd
get what appear to be two separate filesystem trees, but only take up the
space of the original + differences, and a list of the differences (by
running rsync with -v).  You could select which files to keep at that
point and then erase the "duplicate" tree.  This is discussed in the
context of incremental backups at:

If you go this route, be sure to use J.W.'s new --link-dest option as it
keeps the permissions straight.
