I never did this. So please research using the following as hints.
dpkg-divert(8) seems to be the answer for your case. (But this is not
meant for general user but meant for maintanance script). As I
understand, removing divert etc has some pitfalls if you are as good as

Another one is dpkg called from apt has hooks. APT.CONF(5)
There, you may to smart things.
Read tha manpages :-)
