WTB - Pad combined with Arcade case

So I have a bespoke request, Im looking for someone to create the equivalent of this:

But with 8 buttons (ideally).

As for the sacrificial offering (pad) for such a project, I do have a saturn pc pad though Im not sure if internally combining with a brooks universal board is possible.

If a PS4 pad is specifically required then I have a few suggestions.

I am based in the UK but finding it difficult to source a local modder for this request. So open international modders.

You can definitely put Brooks UFB in it, but it’d be in the right side where the buttons are. The Saturn pcb would be sacrificed to gain access to the contacts and traces.

Is anyone able create this for me?

If so please PM as Im quite keen.
