Be sure to include a link to the definition of "mundane SF" so people have some idea of what you're talking about. Also, be aware that the word "mundane" has long been denegrated by SFnal folks: "Mundane" usually refers to the non-SF people who are incapable of viewing the universe outside of their little life's confines, and "mundane fiction" usually refers to the "college literary" genre with its tiny concerns and hopeless attitude toward life. Many mundanes fear and loathe SF. So what a strange thing to want to call your approach to SF!
Yes, I realize this is playing right into the hands of those mundaners, getting the word out on their silly notion, but that's a small price to pay for the fun!
