Without strafe capability, I don't see an advantage that justifies the two extra drive trains.
A tricycle layout might be interesting. you could drive the rear wheels and pivot on the front wheel. If you replaced the front wheel with a single swerve module, then you restore the holonomic drive capability. The fact that there are three points of contact eliminates the need for suspension in most cases.
