   add_action( 'wp_head', 'replace_shortlink');
   function replace_shortlink () {
       // make the new shortlink here somehow, for example, this is what I used:
       global $post;
       if ( !empty(SHORTDOMAIN) ) {
           $short = SHORTDOMAIN . $post->ID;
       }
       else {
           $url = rtrim( get_bloginfo('url'), '/' ) . '/';
           $short = $url.'?p='.$post->ID;
       }
       printf ('<link rel="shortlink" href="%s" />%s', $short, "\n") ;
