Huh, interesting scenario.
Though it does leave me wondering whether such scenario will work all that well tbh.
There would need to be a huge reason as to why Shani would stay loyal to the Queen and being in conflict with Zaton.
Something like the Queen holding Zahra & Ain hostage might just be enough reason for me to force Shani to follow the Queen (into fighting her dad. Anything less, I'd say probably isn't giving Shani enough credit), but even that has its problems (such as if the Queen somehow has Zahra and Ain hostage, why would she even need Shani at all? She can just control Zaton instead).
So yeah, interesting idea, but I just get the feeling it will be hard to pull off in terms of narrative.
In terms of anti-Stalker, something which came to my mind; it might be interesting if the Queen somehow got word that Zaton's master is alive and tasked Zaton to eliminate him.
