Why, though, are you insisting on 100% wool? Just from a maintenance standpoint a basically wool sock with a small amount of synthetic to help it keep it's shape and give it enough of an elastic quality to keep it from sagging while worn seems to be much more practical.
I seem to have better luck with pure wool than with blends. I own at least three pair of 100% wool kilt hose, and when I wear them, my feet are comfortable all day long. But when I wear kilt hose that are only 60% wool (which seems to be about the norm), with the rest of the content being man-made material, I find my feet getting hot and sweaty and feeling slimy in my shoes.

My hands and feet sweat more than most people, due to a condition called hyperhidrosis which I inherited from my mother (and her mother as well). All my life I've had to avoid socks with man-made fibers because they are not kind to my feet.

And this is why I'm doubtful of the idea of sock liners. Knowing my issues with these types of materials, I'm afraid they're going to do more harm than good. But I'm willing to give them a try for hiking, where the condition of my feet is critical. If they help wick moisture away, great! If not, I'll have to revert to what works best for me, which is pure wool with no man-made fiber content.

That's the goal for me at this point, anyway.

Wool hose - Here I'm a bit confused. How much of your concern is aesthetics vs. function? I go for all function, and I only use SmartWool. Bar-none, the best sock for your hiking, mountaineering, and skiing needs.
Actually, I'm trying to find the best balance between aesthetics and function. There are undoubtedly some great products out there for hiking comfort, but they won't be suited to a traditional kilted look. I can always go to those products if comfort and functionality must take precedence over style. But I'm hoping I can find a set of hose and/or sock liners that will give me the best of both worlds.
