Kodak Ektar H35 Prototyping Idea.

Hey all, I have an idea for a film camera idea, but I have no idea in hpw to go about it.

The idea is that take the "half film" idea of the Kodak Ektar H35, but do a version that has no flash, and rather then having a fix lens like Kodak Ektar H35. Have a lens mount. Either Canon RF, EF-M L, E, or X mount. That way it would open up the whole half frame thing to a wider range of lenses. Also as part of that. Have it so the lens mount can be unscrewed, turned 90 degrees, and re-attached to the body. That way for people like my self that use anamorphic lenses. We can use, let say, Sirui Saturn animorphic lens, and get more of a sqare aspect ratio to the image.

How does anyone go about about in getting in contact with someone that can do this as open source project? In that once the end project has be done. Upload it to somewhere like GetHub. That way anyone can download it and send it to a machine fabicator shop. Get them to make all the parts for to in term make it at home.
