That's really more what I was suggesting.

There must be some class that would let us do something like this:

ob_start();
// Existing feed stuff
$xml = ob_get_clean();
$feed = new WPXmlDoc($xml);
$feed = apply_filters('feed_xml', $feed);
$feed->output();

...

add_filter('feed_xml', 'my_feed_xml');
function my_feed_xml($feed)
{
	$feed->data['rss'][0]['customtag'][0] = 'test';
	return $feed;
}

Or something.
