I am not positive, but I believe you can probably do this with API. I know you can get the feature name with API, but then you would have to fire up a thrid party application to translate the text and then send it back to rename the features. An alternative to using a thrid part program would be to have some sort of custom dictionary in a note pad file that could translate the more common terms, that might be the easiest way to translate. Either way it would be a project, but it sounds like you will be needing to this often so it may be worth while to go for it, or find someone to create the macro, I am sure it would cost a nice penny but sounds worth it to me.
