I think that many of these ideas are fantastic and many people (and engineers/researchers and most importantly cp afflicted people) would like to see these ideas come to fruition. I propose making a website or a cyber organization that can collaborate in developing these ideas into prototypes and hopefully into products.
As an engineer myself, I see lots of room for improving the quality of life for loved ones with cp, even if it is not a massive number.
So my idea is to create an innovative design team (even if they are not in the same geographic location) to tackle these ideas and realize them.
It would be a website that would call for innovative people and probably many engineering disciplines (mechanical, electrical, etc). This way people can collaborate in bring new inventions to life.
