I think the Mobius user that goes by FRO did something like this.
He uses a set of scripts that maintain state in global variables,
then advances from one state to the next using one footswitch.
He displays a non-decaying message in the UI to show what the
current state is.  I seem to remember at least one other user 
trying this but I don't remember the names.  

It works but I would imagine that if your performance doesn't
go exactly right it would be complicated to script the right
undo steps so you can start over.  Or if you forget where you
are something "unexpected" might happen.
