I don't see how this could be implemented via a dpkg hook.
Can you elaborate, maybe provide a hook file which implements what you
have in mind?

That said, also keep in mind, that the inhibit mechanism does not work
if the reboot request is triggered by privileged users [1], e.g. if you
trigger a reboot as root, an existing inhibitor blocks are ignored.
