Possible Siren DLC?

Well I was thinking in the allusive Borderlands 3 one of the DLCs should be siren based. Since there can only be 3 sirens in the world at a time, the main villain is making artificial sirens. By using the DNA from Lilth and Maya to take random girls and turn them into 'sirens'
And you're main idea is to stop the 'siren army'
Along with all the other characters in BL2 and stuff like that
Personally I would love to play a DLC like that with different siren abilities like 'phase pet' which would work like Deathtrap
