No, because a roll back of a file can happen on any update. If a file is 
changed in release n-2 and rolled back in n-1, if you only consider packages 
1 n-1 and n you miss the roll back for the people who updated to n-2 but 
missed the update to n-1.
So the system that will create the deltas must have access to every update 
published since the release, or at least maintain a list of all the files 
that changed in any update. And not only changes in the files themselves, 
but also to their meta-informations, like ownership and mode, and other rpm-
related meta-informations like %doc or %config.
