[Plugin: SimplePie Plugin for WordPress] multiple templates on page?

I have a second instance of simplepie elsewhere on a page and wanted to use a different template for it – is this possible?

<?php
echo SimplePieWP('http://website.com', array(
	'items' => 5,
	'cache_duration' => 1800,
	'template' => 'website.tmpl',
	'date_format' => 'j M Y, g:i a'
));
?>

But I get the error:
The SimplePie template file is not readable by WordPress. Check the WordPress Control Panel for more information.
