Well I still dont know what you mean, because skiing it is even easier than hiking it.
From Stowe to Smuggs it's downhill and if you keep your speed you can make it basically gliding the entire way. From Smuggs to Stowe it requires some light xc skiing over a small section of the pond & then a few hundred feet of uphill skating, but it's not a big deal at all for anyone Intermediate or higher. I dont see why you think this is so "very challenging" of an ordeal. Have you ever done it?
Maybe I should have been more clear that when I said "hiking" I was referring to any form of travel using your legs/feet (including skiing) as compared to using some form of mechanical travel (a lift, shuttle, etc). How "easy" the hike/ski itself is does not matter. Even a 5 minute hike across flat terrain will turn off many (or most) people. You're not looking at this from an "average" skier perspective. You will never be able to market Stowe/Smuggs as a single mega resort to the general public if you do not have a lift. And that simply is extremely unlikely to happen at this point.
