modify language codes after the fact

Hi all,

I run a monolingual site, but use qtranslate because I have content available in both the language’s native alphabet, and transliterated with English letters. The language is a minority language spoken in the US, and almost all of my visitors are in the US (so no pre-existing 2-character code). Because I called the transliterated version “en”, the normal default half of the site doesn’t appear on search results in Google (or Bing…) when the searcher is in the US. Since nobody searches in this language using transliteration, this is a major problem.

Is there anyway that I can switch the language codes used in these two languages? E.g., qq becomes en, en becomes qq, and have the content not disappear? Alternatively, is there anyway to have the site in one language but tell Google that both should be indexed as though “en”?

Thank you!
