Late to the party here, but I see that you’re familiar with MIDI Solutions’ products. Their Event Processor, and Event Processor Plus, can re-map incoming Program Changes to CC messages. You’d need to configure one ‘event’ to pass-through the Program Changes received from your MIDI controller. A 2nd ‘event’ re-maps the PC to CC; any CC value, any MIDI Channel.
Ten sequential ‘events’ are available to the Event Processor; 32 to the Plus. One more piece of hardware in the puzzle, but within the same footprint of your Foot Controller.
