I do not think so. XCLASS only works where an object has been created
for a class. For libraries this is not always the case.

And some t3lib files do not have the
if (defined('TYPO3_MODE') &&
$TYPO3_CONF_VARS[TYPO3_MODE]['XCLASS']['t3lib/class.t3lib_tsparser_ext.php'])
{
	include_once($TYPO3_CONF_VARS[TYPO3_MODE]['XCLASS']['t3lib/class.t3lib_tsparser_ext.php']);
}

at the end.

E.g. the class.t3lib_div.php cannot be extended. Another solution would
be needed.
