Then you're correct: filters won't help.

Not really. If you look at `org-latex-publish-to-pdf' you will see that
publishing is done differently: the binary file is generated, then
published as an attachment.

Sort of. `org-export-filter-final-output-functions' will get you the
final string, along with the info plist. You can use it to apply
modifications and generate the binary file. The original output can then
be discarded.
