S'mores cake, does this sound good?

I want to make a cake with a s'mores theme. I was thinking chocolate cake mix (b/c i'm lazy), mixed with crushed graham crackers and mini marshmallows with fluff mixed with graham crackers for icing with broken hershey's bars on top. so does anyone think this will work? will the graham crackers and marshmallows in the batter turn out okay?
