There's a history of bugs in rsync with --delay-updates. One of them
has been corrected only in 3.0.5.

No, unfortunately not. You can't scan just repodata/ in the second
pass because rsync won't remove anything outside it, ie. the packages.
You have to sync everything again, which means you double the scans...
Not feasible IMO.
