Taste of Home has a recipe for Corny Snack Mix. The ingredients are popcorn, corn pops, corn chips, and vanilla or white chips (the ones like chocolate chips). I know the corn pops are not gluten free, but everything else is (remember to read ingredients). I think some gluten-free cereal such as Gorilla Munch, Panda Puffs, or Rice Chex could easily be substituted for the corn pops. Sounds like an interesting recipe to me. Let me know if you give it a try.
