In this situation, your forward or direct traction would be similar to that of a standard four wheel drive, but laterally against the faces of the wheels, your friction force would be about half. It also changes your center of rotation, but making a 6wd with two front omnis would be a good compromise: wide wheel base for 4 traction wheels and the stability of a 6wd.
