There's going to be some things I agree or disagree with. I'd say if he survived that and was with Luz, her friends and all, I can kind of see him trying to adjust to the human world and he'd have some comedic mishaps that could be funny.
But when they return to the Boiling Isles. I'd say that Amity would still be the one to force Boscha to stop Kikimora and save Luz because I think that someone bully brat Boscha has bullied being the one to force her to help out is more satisfying rather than it be an adult doing that ( Boscha was always a hatesink that was never meant to be redeemed and she never was and never will be redeemed or reformed as there's no official proof and nothing proves it. Same is said for Odalia ) we all know that talking some sense into Odalia will never work and the time for that has passed. Odalia was never going to realize the error of her ways as she is a hatesink as she was bever kinder in the past. All of Odalia's actions were never mistakes, she did them all on purpose. Even Alador knows that there's no changing Odalia at this point and Odalia will never change because she doesn't want to. She's pure evil.
I'd probably see that Alador would make jokes about Odalia being reduced to being a servant or a nanny to The Collector as her plans went south. But it would make it more satisfying that Alador shows he no longer fears Odalia and he takes her down ( not murder her, no )
More like he stops her completely and Odalia is defeated for good like Azula was when Zuko finally put her in her place. Something about Alador doing that when confronting Odalia just seems more satisfying and realistic.
But maybe when Odalia is about to be defeated, she'd say "Oh come on, honey, we're married" but once she tried to give a sneaky final move, Alador ends up defeating her for good like I've described and Alador would say something like a cool one liner by saying "Consider that a divorce" going all Arnold Schwarzenegger on that would sound cooler.
