Actually I am all for disguising a look pre-snap. Packers don't do a lot of that. Wist may be haunted by the 2-4, but I am haunted by Eli Manning saying its not like he had a tough time figuring out what the Packers were doing (Kurt Warner also said this) in coverage.
Hide it, show zone then run man. Show single high then retreat to two deep. Reverse it. Stand everyone is the same position every snap then have them run to assignment at the snap. Change all the uniform numbers. Maybe camouflage.
