With enough cover and places to hide, it might work for weeks or months, but there is a risk. I've seen a 6 inch O. scyllarus take out an 8 inch clown trigger. There is also a risk to the mantis shrimp. Generally, I would not recommend keeping to large predators in the same tank.
As for aggression in males and females, no difference. There is far more variation with changes in the molt cycle than you will see with sex differences.
