I can only think of one spot that has all the key elements: top quality skiing and climbing, a half day from the road and not within an established Wilderness: Silver Star basin. Still would take a hell of a lot of red tape to get it through and it’d be a damn long drive during the winter.
As to whether we actually need any huts in the Cascades, I’m in complete agreement with Goatboy (way back there): Huts are a nice change, but for my local mountains, I’ll happily live with the protection provided by the Wilderness Act, despite the few limitations it puts on us climbers.
