why just add a hook for extSaveFeAdminConfig, for example like this
if 
(isset($GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tsfebeuserauth.php']['addCCS']) 
&& is_array 
($GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tsfebeuserauth.php']['addCCS'])) 
{
		foreach 
($GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tsfebeuserauth.php']['addCCS'] 
as $classRef) {
			$hookObj= &t3lib_div::getUserObj($classRef);
			if (method_exists($hookObj, 'addCSSforFE')) {
				$GLOBALS['TSFE']->additionalHeaderData['fe_edit_css'] .= 
$hookObj->addCSSforFE();
				}
			}
		}

I added some for the hook some params, in order to avoid resetting 
configurations.
