I think the problem is getting white out/blizzard conditions and 24" or more of snow in one storm at that sort of elevation. In that case, "keeping up with it" isn't really going to be an option.
Have you actually found houses at 7-8k feet?
Around here, even at 6k+ they just don't get those crazy storms often, so once every few years, you might have to plow continuously during that storm.
Even if you had a tracked rig, a storm lile that could drift areas enough to be impassable or very sketchy, so it just puts you back to the only reliable way being clearing the snow.
