Is there a possibility for another Darkin champion?

I'm so fascinated by the Darkin race. I would like to see the rest of the Darkin's (the other four). If any reds want to put there input into this, please feel free to. Also, speculations are welcomed and any news are welcomed by people. Champion concepts are also welcomed. My concepts will be listed. All in all, I would like to hear more on if there is going to be a future Darkin champion. Aatrox has been out for a while, he needs a comrade. My concepts: Aazulthra, the Betrayed Darkin Keirr, the Elder Darkin
