I do not think this will work with the new exporter.  A filter gets
three arguments: contents, backend, and info.  `contents' should be some
LaTeX snippet as translated by ox-latex, backend is the latex symbol,
and info is a plist (not sure what is in there :-p).

Your function above doesn't conform to the above signature.  You can
take a look at <http://orgmode.org/worg/exporters/filter-markup.html> to
get a clearer idea.  I still have to go through it myself :-p.

After you have devised a compatible filter function, you should be able
to add it to org-export-filter-headline-functions.

Hope this helps somehow,
