Yes
No
I will say that if Hickman is building up to some kind of confrontation with The Pretender then the Eichmann parallels are almost certainly going to be brought up by someone. (Probably a "villain" like Exodus, since Hickman likes to put controversial statements into the mouths of unsympathetic characters so we can argue about whether to agree with them or not.) If she's been built up as this enemy of all mutantkind then someone is going to want to kidnap her and bring her to "justice," and it's not like she hasn't already been kidnapped 13532teen times. She's super easy to kidnap.
No. She shouldn't. We don't care about villains doing bad things in this era, or something like that I am told.
I think that if he's going to have characters defame her and cover their ears when her name is mentioned I'd at least like to see her show up. That would mean some mutants would say nice things about her, just to create conflict with the ones who (rightly, in your view) detest her.
Just on a sales basic I think a story where the "No More Mutants Lady" shows up in X-Men would sell copies. Even I admit that adding Wanda back to the Avengers where she belongs wouldn't boost sales much. I'd just rather see her in a comic that sells and if it's not going to be Avengers then I'll take X-Men.
Both Avengers and X-Men do fine sales wise. Wanda just needs her own stories, or back on the main team. Her popularity these days are from the films. That's it.
Love is for souls, not bodies.
