The Seventeenth Letter

Yet another idea for my novel: A novel about a man writing a novel that never uses the letter Q. Why the letter Q? Because I think that I could write a great deal without ever using the letter Q. And so whenever I had trouble writing about the guy writing the novel, I could switch into an except from his novel where the only rule is no Qs. I don't know if this is a good idea or not, but I sure did enjoy Michael J. Nelson's Death Rat, which is another novel about a man writing a novel, so I think this idea could work.
