I really like your notion and the coloration of the tartan. What about a more weathered look perhaps. A difficult balance as you know the colors in this region are very stunning and dramatic, at the same time they really change thru the seasons. I think it depends on which season you would like to focus. The greens here are not at all subtle in the Summer. They almost shine with the light. Of course I would favor a late Fall look that was very weathered. But then it would look some like an ancient Buchanan tartan which I suspect we both like. Either way looks like fun and a good idea.
