You could use database driven routes.

Add the table blog_slugs to your MySQL database:

CREATE TABLE IF NOT EXISTS `blog_slugs` (
  `id` bigint(20) NOT NULL auto_increment,
  `slug` varchar(192) collate utf8_unicode_ci NOT NULL
  PRIMARY KEY  (`id`),
  KEY `slug` (`slug`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1;

Replace the code in application/config/routes.php with the one below:

$route[ 'default_controller' ]  = 'main';
$route[ '404_override' ]        = 'error404';

require_once( BASEPATH .'database/DB'. EXT );
$db =& DB();
$query = $db->get( 'blog_slugs' );
$result = $query->result();
foreach( $result as $row )
{
    $route[ $row->slug ] = 'pages/slug_on_the_fly/$1;
}

All you would have to do then is to create a record when you create a blog entry and you're done:

INSERT INTO `blog_slugs` (`slug`) VALUES ('name-of-the-article');
