You can certainly specify all your aliases in the request. The request handler is just there to simplify the client by allowing it to specify a different URL with everything else mapped on the server. And, of course, with request handler you can lock the parameters to force them.
Regarding language detection during indexing, there is a module for that: http://wiki.apache.org/solr/LanguageDetection . Hopefully that would be sufficient. Regards, Alex.
