The required torque to get a Mecanum wheel to move sideways certainly increases with additional weight. I think that can be addressed somewhat by making the rollers spin a little freer.

Why do you think squareness is an issue? The center of mass should probably be as close as practical to the center of the 'bot in order to keep weight equalized on all the wheels, but I think a long or wide rectangle ought to work fine.
