No, I've never done one for the original battery. You can always reflash the current language pack which will have the same effect. However, if you have any theming other than the built in miui system, you would lose that.
When I was making up the 12.11 releases, I noticed some problems with the white version that I didn't like. And when I dug into it, I found even more....so I trashed the whole folder to start over. But, I haven't gotten started on it yet. I've just been incredibly busy with other projects. I'll try to set aside some time to rebuild that battery, but it will likely take some time to make it to the standard I'd ideally like.
