House Rule discussion - Reserving of Super Heavies

Thanks to the latest BRB FAQ, a unit entering play from Reserves which can not get fully on the table in its Movement Phase is Destroyed. This means (non-Walker, non-Fast) Super Heavies can not enter play from Reserves because they are usually over 6" wide/long and only move 6" per turn.

I'm OK with Super Heavy Tanks not being allowed to be held in Reserve, but there are Formations with Super Heavies that provide Flank March and that benefit becomes useless given this approach. Comments, suggestions?

Super Heavy held in reserve should come on the board in there narrowest profile to fit within the 6 inch movement or alternatively move at there fastest speed to come on the board. I know that would limit shots fired but it would make solid sense.
