The main thing I see that's missing is something in between running shorts and shirt and the full winter/rain gear for hiking. The microfleece or the baselayer stuff would be great at night, but I would roast with any of that stuff during the day (Sept/Oct) hiking in the White Mountains. But, if you get caught on a raw drizzly or windy day, you'll freeze in the shorts.
I would trade out one of the baselayer tops for the coolest possible long sleeve tech t shirt — something that can pass for a running shirt with the sleeves pushed up, especially since you've already got the duplication of the baselayer top and the microfleece top.
And, a glaring omission seems to be a wind jacket. The clothing I am most likely to grab on a fall hike in the Whites is a lightweight wind hoody (Houdini, Marmot Trail Wind, etc.) Just enough to break the wind. I love NeoShell, but that's way too heavy for that purpose. You'll roast if you need to wear it on the move.
Also, as much as I hate them, this would be a prime candidate for a pair of zip-off hiking pants that give you the option of shorts or long pants. You could expect some hiking temps in the 40 to 60 degree range that are a bit cool for shorts (if you catch a gray or windy day), but not cold enough for baselayer tights. Lightweight summer hiking pants seem just about perfect for fall conditions in the Whites.
