I'm thinking this could be altered a bit to make a pretty tasty pie. I'm thinking good cherry filling with a dark chocolate ganache on top. I've also had chocolate with a creamy blueberry filling that was very good (See's Candy Blueberry filled Truffles, yum). There are many other fruit fillings that I could see working with the chocolate-rise cereal crust, such as banana, strawberry, raspberry, pineapple, or even fill with a butter pecan type filling. You could almost make this into a s'mores type pie as well.
Ain't imagination a wonderful thing?
