I attempted to do something like this for OpenDocument files (I didn't get
very far) until I discovered that LibreOffice can save "flat open document
files". That combined with the option "save files optimized" switched off
results in fairly readable XML in a single file that can even be merged
under some circumstances.

You would still need a clean filter that normalizes the style numbers,
cross reference marks and other stuff that changes each time LibreOffice
saves the file.
