Actually, you won't. I just finished debugging it.
I'll leave it up to you to create the TMPDIR or change the path in the
script

#!/bin/bash

TMPDIR="/tmp/x"
DPKGINFO="/var/lib/dpkg/info"

for i in $(dpkg --list | grep ^ii | cut -f3 -d' '); do
        echo "Now rebuilding package: ${i}" 
        sudo apt-get -d install --reinstall $i -qqy
        DEBNAME="/var/cache/apt/archives/${i}_*.deb"

        # extract control information
        dpkg-deb -e $DEBNAME $TMPDIR

        # we don't actually need the control file itself
        rm $TMPDIR/control

        # but we do need a file list
        dpkg-deb --contents $DEBNAME | cut -f2- -d'.' | while read k; do echo "${k%*/}"; done > $TMPDIR/list
        echo "/." >> $TMPDIR/list
    
        for j in $(cd $TMPDIR && echo *); do
                mv $TMPDIR/$j $DPKGINFO/$i.$j
                # $i.$j = packagename.postinst, for example
        done

        #wipe clean, save space
        sudo apt-get clean
done
