Similar to the Helicon 6 button footswitch, you could have more control mapping so it could be easier to use on stage (but it is already pretty easy). 6 buttons could be a good expansion beyond 2.
How about a midi footswitch?
+1 vote for midi in control.
+2 for midi in control!!! It would be FANTASTIC live to be able to pause, accent, stop, and access a special song section(aka, bridge) with one tap instead of trying to remember the super nintendo cheat code. up up down up right left right left doesn’t work great on stage 
left-down > up-right + B
Having only 1 pedal + maximum of 2 footswitches is indeed a bit inconvenient. Most likely analog footswitches can eventually get replaced with MIDI-based ones.
I can tell someone else played the same games as me growing up
