Iirc the policy specifically excludes conffiles from this. As in one
package is not allowed to meddle in another packages conffile.
But it should work (I'M NOT SAYING IT WILL). Older dpkg would refuse
to install a package that didn't give up a replaced file (trying to
overwrite file error) but newer dpkg remember the replaces line and
ignore the replaced files. That is how it works for non conffiles
anyway. If conffiles break with replaces then I guess you should file
a bug and hopefully patch for this, despite it being policy
non-conformant.

I tried this once and I setteled on writing a package that would fetch
my conffiles from a RCS. On initial install it would just check them
out and dump them in place. On updates it would update them to the tag
coresponding to the package version. If you have different configs per
host you can create branches for each host and fetch from there.
You can also add a hook to run post dpkg that will compare the state
of conffiles with the RCS and warn you about changes.
