Alias sitename/xx to translation of front page

I would like to have http://sitename/ direct to the english front page, http://sitename/de go to the German front page, http://sitename/fr to the French etc. Is there a way to alias say http://sitename/de to a node of my choosing?

There is sometimes an assumption that http://sitename/de will take a user to the root of the German site, so I would like it to do that. Unfortunately, aliasing this path in the standard way does not work.

I think it would be reasonable that this path can be aliased.
