Hello Peter and welcome to the forum.
I'm familiar with Viscount (as they are their touting modeling technology vs sampling) but not their actual hardware per se. Glad they are offering an AGO MIDI pedalboard as a separate purchase item. Your tag doesn't show where you are located. If you are in the US, alternative sources for MIDI pedalboards would be Classic Midi Works in Canada and Custom Organ Works in Minnesota

If you would like to build your own organ as you posted, try finding an pedalboard off an older console and MIDI-fy it yourself. Once in a great while I see older 2 manual organs for free or maybe < $200 where the pedalboard is salvageable. Here is a video of showing this kind of project:
