I think of the wing the risk is probably relatively low.
Sure you needed to have the idea and make a prototype but materials are known, design easy compared to a kite and production is probably very similar to a small kite.
The only real risk I see is in inventory: you build to many of them and you cannot get them sold.
I would not be surprised if building a (mass production) aluula kite is actually harder to figure out even if you could just copy the kite design.
You need a factory that can work with this new material and things that are trivial/known with Dacron might know cause issues in production.
Also you run the risk that the material is not suited for kites after all because of sand/salt/sun/whatever causes issues in the real world.
