You can't change the pedal sequence on just about any foot or rack loop switcher. The only one I can think of that can is the Sound Sculpture Switchblade, which is pretty old technology at this point. There should be more switchers that do this by now.
I'm kinda shocked to read this (I believe you, just shocked)... I mean, I've drawn up a diagram were I can switch the order of effects with 3PDT and 4PDT true bypass switches within a 10" strip. How in blazes could a digital switcher not do this?

). This is what I have been expecting to see at some point. Heck the M13 does this to some effect with its effects loop.
