I try to look at things from a marketing perspective. I haven't figured out how you want to market this material hybrid. Mixing materials just for the sake of a mix isn't destined to make a viable product. Give some thought to the why. What would motivate a bicycle manufacturer or a bicycle enthusiast to buy this mix instead of another? To put marketing into the simplest terms it is the process of 1. finding what people want, 2. getting it for them and 3. telling them you have it. I'm not sure you've even progressed to step 1.
