So someone gives you a “coded” message with a ? mark at the beginning, you will very likely assume it’s backwards.  Oddly enough, I never considered it for K4 until now.  All of this K3 transposition crap is what made me think of it to be honest.  So, maybe I’ll play around with a backwards K4 for awhile.

I’ve had dumber ideas before.
