I don't know 'demime' so the following is completely untested and
perhaps broken, but I use something along this structure with a
python script, so perhaps it gives you some ideas:

define demime ()
{
  variable art_as_string = article_as_string ();
  variable fp = popen ("echo '"+art_as_string+"' | /usr/local/bin/demime", "r");
  variable art_demime = strjoin (fgetslines (fp), "");
  pclose (fp);
  if (art_demime != "") replace_article (art_demime);
  else error (_function_name () +": failed");
}
