I have a new idea that will fix everything, I hope.
What if Godzilla were an Event Hero that used 2 figures to represent 1 figure?
Instead of requiring a complete figure of Godzilla, we decide on and craft a left and right foot of Godzilla that is available to all interested, at a reasonable price.
Each foot takes 2 hex bases, but its toes and nails take up additional space, which must be considered with its movement and Wake of Destruction power.
These two feet must be within x distance of each other to perform x move. Must move in a certain way. All figures on the battlefield have clear sight of Godzilla.
We can go so far as to declare that no figure has height advantage on Godzilla unless they used Flying to move.
