Interestingly, the cantaliever only slightly affects the factor of safety.
Of course, if they want to run something lie 24" wheels, then I could see tool steel being a valid choice. But before doing that I would just increase the axle diameter.

EDIT: Actually, is tool steel even capable of taking axle type loads? It might be too brittle.
I know teams that used steel axles this year that had bending issues with aluminum and mild steel. Progression of materials landed them at tool steel. Calculators have issues with being based in theory. The problem with theory is that it doesn't always jive with reality.
