Don't see why you should need 4 extra pedals though, just 3 for minor, dim and aug.
The 4 switches for maj/min/aug/dim are actually attached to the volume pedal that the right foot operates. The toe of your foot slides either left or right to access the top two switches, and the heel does the other two.
Still sounds like a lot of work to me.
