To show you how crazy I am, I actually started a process to put together a hut system above Huntington Lake out of Fresno, maybe 10 years ago.
My idea was to use existing buildings, and convert them into appropriate winter shelters, somewhat like Ostrander. The local USFS guys were supportive of the idea, I don't remember why it finally fell apart. Inertia kills a lot of things.
I suspect that such a system would be very popular.
