I see. To do this, but I have a Soleman, I use macro for each scene and various midi channels, the scene is recalled by a global PC then PC (for my amp) and CC are added to change 'special pedals' to something else than what is stored in the scene. But I see your approach is quite the same. For me I am far to exhaust the 128 scene values and I have so many pedals that scenes are the only way to not get crazy in CC. And doing this stops any possibility to share scenes, which may not be the intention of everybody, not blaming.
