The reason you can't turn in conventional crab is because the drive is all chained together and because the wheel scrub from trying to tank turn is too significant.

here's a crude vector diagram of my 3 wheeled swerve rotating.

If they were traction wheels the steering would be awful (non existent) because the wheels would oppose the lateral forces exerted on them. With omni wheels this does not happen so it should be able to turn quite nicely.
