I think Luke was comparing your 2-wheel arrangement to a swerve with only one wheel centered on the turning axis. In that comparison, it takes much more torque to steer the 2-wheel arrangement. Also, the kinematics with the 2-wheel arrangement are slightly compromised: there will be some wheel scrubbing.
Have you done calculations on the loading of that bevel gear bearing? It will see thrust, side, and cantilever loading.
