Dahak's other notable minions, listed in Inner Sea Faiths?

[Colette Brunel]

Are there any plans for Dahak's other notable minions, listed in Inner Sea Faiths, to make appearances in this adventure path?

I am talking about Aashaq the Annihilator (CE female great wyrm red dragon cleric of Dahak 7), Emissary Rixmar (unique contract devil), Kronoroth (herald of Dahak, unique ancient white dragon), and the Roiling Mass (unique Medium magma elemental).

How could these be integrated into the adventure path? What would their respective creature levels be?

Rixmar could sneak into the Ravounel-set volume?
