2 very light items you may want to substitute for those extra meals: powdered potato flakes,(high carb, good fuel lightweight food) and a Ramen or two (you may get sick of your snacks and appreciate hot soup on a rainy day)
I agree you may not have the huge appetite of the NOBO hikers unless you have been training hard in which case you will probably move faster.
Have fun. sounds like you are planning it well and will eat better than most.
