Piranha props would be a nice spare, but in trying to find the most efficient set up for a rig of the size and horsepower mentioned here there are many many many more options in steel props.
Piranha props are made using the same design for each fin, but in different pitches. The ability to have more raked fins, cupping, vent holes, etc are not available. The composite might be stronger than aluminum but it will still flex quite a bit more than steel, which reduces its ability to bite the water well. That equates to not being able to play with motor height and the motor itself will not respond as well to trim.
It would be a good prop, but in my humble opinion, best left to be a spare
