I do not know if this is what you are expecting, but here it is. I come from the satire of gender roles angle of omegaverse generally.
So, one of the things that made me tilt my head reading the DA codex was reading that Azrael reacted to Asmodai going way overboard by putting him in charge of the most impressionable members of the entire chapter: the neophytes. In canon this is weird because neither Azrael nor Lion nor literally anyone else in the Inner Circle has any reason to want more Asmodai, and this seems to be a great way to get more Asmodai. Sure, there’s the element of it being a demotion for a guy who by seniority and skill has a decent shot at being head chaplain, but still—wouldn’t ninth company have worked?
Regardless of the canon reason, this combined with a recent omegaverse kick in my fanfic reading habits has led to a very silly theory as to why this could happen in an AU: Asmodai would be an omega in the omegaverse. I don’t think there’s any DA omegaverse in a language I can read but I hope those fine authors focusing on that matter see my reason. It’s about the neophyte thing.
Now he’s not a good omega. But I can see a very fed up Azrael and Ezekiel brainstorming ways to get him to chill out with the blowing up cities and going “omegas like pups right. Go shove him at the neophytes.”
Much like I assume happened in canon when Asmodai was reassigned to tenth company, disaster ensued. Dunno what happens after that point, but I assume eventually Lion rolls up, beholds his terrified youngest sons, and realizes he has no idea how to deal with misbehaving chaplains other than slapping their heads off.
