Preheat oven to 350 degrees F (175 degrees C). Grease an 9x5 inch loaf pan.
In a large bowl, stir together the mashed banana, eggs, oil, pumpkin, honey and sugar. Combine the flour, baking powder, baking soda, salt, pie spice and cinnamon, stir into the banana mixture until just combined. Fold in the raisins and walnuts if desired. Pour batter into the prepared pan.
Bake at 350 degrees F (175 degrees C) for 45 minutes, or until a toothpick inserted into the center of the loaf comes out clean. Cool loaf in the pan for 10 minutes before moving to a wire rack to cool completely.
