Well If they had used the make-up prostetics from the show and scanned the actor it wouldn't be that hard to begin with.
I think she would screw Nolan over and steal the shtako he took form Varus, Nolan does mention him in the pilot episode. The crappy thing is because shes an integral part of the game she would never be in the show permenantly.... Unless they decide to shut down the servers.
It might be worth it to Nolan to trade some time with Cass for shtako he took from Varus. But yeah, she is too present in the game to be a main character in the city. But I think it would be fun if she came in for supplies now and then and hook up with Nolan, sure. Although if it would be more or less fun then the time he apparently had with the duct tape... I really liked how casually he was stripping it off in front of her sister. On the other hand Cass might hook up elsewhere and raise so much ruckus as it was mentioned she was a hard drinker, that Nolan has to arrest her. A lot of scenarios here. But I would really like some guest appearances. I am
not sure Kenya is dead either. Stama was very unclear when she reported back to her husband and we know how sneaky she is. He could have said 'poison her' and forgot to say 'lethally poison her'. She just said 'I have done as you asked' and NOT 'she is dead'.

I really like Cass, I think both of my characters would get along with her, but I didn't / wouldn't write her into their story since I don't own the character.
I wouldn't mind seeing her in the show, but I'd really rather see Varus somehow. The show needs more attention given to liberata and and sensoths, and Varus is so different from the other ones that it would really make an impact.
It may just be me, but those two races in the show felt really ignored and half-assed, with only very small differences between each character.
