The only AU I can imagine is a Raven Cycle-Harry Potter AU where the raven gang have all somehow managed to grow up to adulthood and become professors or agitators at Hogwarts. Obviously Adam would be teaching Defense against the Dark Arts because it takes one to know one (smirks Ronan as gamekeeper) and he and Ronan would be the source of much hallway gossip because please and I know you’re all thinking that Gansey would be headmaster but you are mistaken as Blue would be the professor of Divination who has only ever had one vision and it is of a muggle named Gansey who has no magical powers but somehow nonetheless managed to defeat Voldemort in single combat while sitting in an Asda parking lot in his Triumph and driving goggles, without getting his khakis dirty.
Clearly Dumbledore would not be dead in this scenario, merely sleeping, waiting for the gang to come find him so that they could all rise up against the Death Eaters, who in this AU are bored computer programmers from Leeds who are just looking for a bit of damn excitement on the weekends because is this really what anyone thought their twenties would look like?
tl;dr I’m a serious author what’s an au pretend this never happened
what i do is not up to you
