I don't know the way to do just what you want off the top of my head,
but I have an idea that might be sufficient (or possibly even
preferable).  If the systems you're setting up are under your control
to the extent that the files you are looking to replace will have
standard content, you could just patch them in the %post section of
your package.  You then wouldn't need to fight with another package
over ownership of the files in the rpm database and once you patched
them to be like you want, if the package that owns them gets updated
it should install the new version with a .rpmnew extension instead of
overwriting it (true for config files generally, but not other files).

Maybe that'll help.  If not, perhaps it'll spur someone here to post a
more elegant solution.
