Code something like this has worked for me to override template 
selection based on what I got into the query variables with rewrite rules:

add_action('template_redirect', 'myplugin_template_override' );

function myplugin_template_override()
   global $wp_query;

   $template = '';
   $q = $wp_query->query_vars;

   if( isset( $q[ 'mycustomvariable' ] )) {
     $template = TEMPLATEPATH . "/mycustomtemplate.php";
   }

   if( strlen( $template ) && file_exists( $template )) {
     include( $template );
     exit;
   }
}

Hope this helps,
