Sounds like a very good idea to me. My suggestion is keep the idea zipperlipped untill prototypes and production can be figured out economically. I had taken an idea and prototype to a Redmond based flyfishing reel company, they told me it was a very interesting idea and they would get back to me. You can probably guess what happened next. I was at Kauffmans fly shop a couple months later and there it was , my product with someone elses name on it. Live and learn. Hope this helps. Best of luck!
