Hi Scott:
First let me say nice tye. I really like it and like your idea. I find it a pattern that I want to give a try. Now here's my thinking stealing from your Idea. I would tye the wing in first and then put in a Full collared hackle to give a little more movement to the fly. I would use a nice coachmen brown hen cape for the collar. I really like the fly and like your tying.
Respectfully
