At this point you've killed enough Primals to fill out a small bestiary worth of summonings. I mean, what elemental alignment ritual would you even use to summon Alexander and Ravana?

Alexander is Light, that's pretty consistent really. And Ravana, as mentioned, is Fire/Earth. There isn't really any elemental issues given Bahamut.
