Working on new surrealist sci-fi story

I'm currently working on an aleternate history of England, where the Nazis successfully invade England in the 1940's and capture the Inklings writing group. Tolkien and Lewis are executed in the story, but without giving into the ubermensches of the Reich. At the end of the story, the Nazis find a graveyard of centaurs and fauns and can not explain where the skeletons came from. Anyway, that's my idea. Tell me what you think.
