Can't you simply use org-publish-after-publishing-hook to copy the
published file elsewhere?

Or, if you write your own exporter, do it =C3=A0 la "ox-latex.el", i.e.,
publish in :base-directory and move it elsewhere with
`org-publish-attachment'?

This doesn't sound right: if you know the file name beforehand, you
don't need to call `org-export-output-file-name' in the first place.
