Well, with that you have just disabled the primary
characteristic of rsync. I'm not saying that a utility that
identifies files that have changed for a compressed remote
storage, just that this isn't rsync.
There have been several proposals that are at least somewhat
consistent with rsync for doing this. Look in the list
archives. Another approach is to create your own utility.
The GPL lets you even steal or build on rsync or other code
for the purpose.
Of course there are also compressed filesystems and
compressed loopback devices or using an existing tool (i
assume there is at least one) that already do this.
