Preheat oven to 350 degrees. Combine peaches, strawberries and 1/2 cup sugar in a pan and bring to a boil. Set aside.
In a mixing bowl, whisk together the first six ingredients, in order. Grease the sides of a large casserole dish. Pour in melted butter, then add batter mix. With a slotted spoon, evenly spoon peaches and strawberries onto batter.
Take 1 cup of remaining juice and pour over batter. Reserve the excess juice to add after baking, if you like a juicier cobbler.
Slice bananas approximately 1/4-inch thick and evenly distribute on top of cobbler. Crush some vanilla wafers and sprinkle a light layer on top of cobbler. Bake for approximately 40 minutes.
When cobbler is approximately 10 minutes from being done, remove from oven, add a thicker layer of crushed vanilla wafers and top with Hershey Kisses.
Continue baking until done and candies are about halfway melted.
