Anyway to set $config['url_suffix'] during runtime?

Your option is limited and its not a easy job. If you want to use hook, you need to "edit"/access the config file at pre-system checkpoint. Its on route section flow, suffix inspection happened. Or if access/edit file its not flexible enough for you, you can hack the URI-class to receive some defined constant from your pre-system hook.
