An aluminum prop is only going to save you if you are in a low speed situation. You hit a rock at mid speed and above, you are almost guaranteed to bend a shaft, let alone lose a blade...
Can damage be less? Possibly, but at speed, aluminum is going to have enough resistance to do major damage to the lower unit.
I have been running steel up there for as long as I have been going up there and have not had any rock issues. Follow your map, watch for contours between islands, etc. and you should be fairly safe. Not all rocks are marked, so it is never a guarantee, but being mindful of the area will save you.
