Is there a mod that changes combines into nazis?

If there isn’t, than i guess this is a request. But how cool would that be? Picture Half-Life 2, except replacing all Metro Police, Prison Guards and Soldiers with Nazi models from day of defeat. and even change Breen into that Hitler model. And of course the voice sound files should be changed, by just replacing combine speech with voice files from day of defeat, because they do speak german in that game.
Who’s up to it? (forgive me if this mod already exists, a link to it would be nice)
