As far as stiffness goes, All aluminum has pretty much the same stiffness. Stiffness is based on Young's modulus, shape & doesn't change much with alloying & heat treatment. Strength is a completely different story.

The concern I would have would be the difference in torque transfer of a rounded off hex & would the shape spin in a round bearing, making it a bushing. I have not looked very closely at this so it is just a concern, not an known issue.
