Your needs are very specific. So, I think you need to write a custom 
script for that.

What we do here is, packaging the custom configuration files (rpm).
The source package (srpm) has also the original or distribution
version of the configuration file. Downloading the current original file
in a pre task and patching it while building the rpm helps us to track
the changes ...
