Here's stunningly obvious connection to explore: postmodernism and cultural studies as two movements in response to mass culture. One arising out of Raymond Williams's Marxism, the other out of Frank O'Hara and pop art. You could say Frank O'Hara meets the late Stuart Hall. The hi / lo cultural divide gets bridged in different but parallel ways in the postwar period, by an academic movement and by an artistic one.
The best ideas are often very obvious and true ones. If someone has done this already that's good. If not, you can use it as your dissertation topic.
