I'm not sure I understand the reasons behind your current (complex!)
method, so I apologise if my suggestion is too limited for what you
need. In any case, I've had no problems using a method like this:

switch ($_SERVER['SERVER_NAME']) {
  case 'www.example.com':
    $page_not_found_id = 123;
    break;
  default:
    $page_not_found_id = 456;
}
$url_pattern = 'index.php?id=%d'
$TYPO3_CONF_VARS['FE']['pageNotFound_handling'] =
sprintf($url_pattern, $page_not_found_id);

Obviously, the two main issues here are:

1) if you have an always-changing set of domains, this is far too
primitive since you'd need to add both domains and page ids, and
2) if your editors delete the pages referenced here, your 404s break
(but you can prevent this by setting the ownership of the 404 pages)
