More than one email address

Would it be possible to add an option to enable two email addresses?

I want one to admin and one to editor, if possible!

Would something like this work?

// send multiple update emails
function XYZ_filter_auto_update_email( $email ) {

$admin_email = get_bloginfo('admin_email') ;
$extra_email = get_option('extra_email') ; // this is an added entry field within the plugin options form

$recipients = array($admin_email,$extra_email);

$email['to'] = $recipients;
return $email;
}
add_filter( 'auto_core_update_email', 'XYZ_filter_auto_update_email', 1 );
