Currently I'm considering Simon Snow, the works of Josephine Bettany, and Johnny Chess and the Starjumpers (assuming they let fake bands in). Maybe the book series from M.T. Anderson's Pals in Peril or the one from the Brixton Brothers, or which was the Trixie Belden where they met that kids' book ghostwriter. Then there's the book from Seven Day Magic and the science fiction novels that Sarah Jane Smith supposedly wrote. I shall have to think on this.
