I did a basic drawing of what I would like the case to look like and how it will clip in. I also added a description of where the ports are located and their individual purposes.

As I hope my drawing conveys It will clip into the rear first then hinge forward to clip into the front. After the case is secured the custom C shaped type C cable will connect the furthest to the rear USB C ports together to transfer data and charge between the laptop and case. Im not sure what I would like the case to be made of but I think a rubber or silicon coated plastic would be super nice.
