PlayStation 1, and Super Nintendo working Asynchronously, and Synchronously

I am looking for an engineer or two, that could design a solution to connect a Super Nintendo to PlayStation 1 and have the latter work in combination. The Super Nintendo would still function on its own, but with the addition of connecting a PlayStation 1, the operations transfer to the latter. Combining power sources, controller compatibility, a/v components, and general syncing of both systems. Ideally, the PlayStation One fits in a plastic shell I have acquired, which would then attach to the auxiliary attachment located on the bottom of the Super Nintendo. Would be a one-off development.
