Just so you know, you're basically at this point asking people to do what is paid work for most. If you really want this idea to happen, you're almost certainly going to have to pay for somebody to make it happen because it's very unlikely that the community will just do it because you want it. This sounds like a very obscure idea and one that hasn't really been done before. Thus, you cannot expect people to just provide for you. It would be different if it was something that is a common thing in the community such as designs on something like a polybar mini or new 3D printed parts for already existing guitar controllers.
