Two would yield a ratio of 12.75:1, just like the toughboxes (both are made up of 14:50 reductions).

Torque/speed is still very much a concern. If you gear it too high, accelerating will take forever and low speed movements will be hard to control.

I have never built an omni-wheeled drivetrain, but I imagine directly driving off of two stackerboxes two 6" omni wheels would yield a decently fast drive, probably around 9 fps (assuming that at free speed, it'd be just shy of 11 fps).
