I’m not sure this is an AU to be honest. I mean:
Bill Weasley: Curse-breaker, works for Gringotts breaking into cursed tombs and distributing valuables to heirs. Ron Weasley both broke into Gringotts itself and destroyed the ultimate cursed object, a Horcrux. Check.
Charlie Weasley: Aforementioned dragon stuff. Check.
Percy Weasley: Social climber, status seeker, desperate for attention and approval from his superiors. Ron: Literally married to the actual Minister of Magic. Check.
Someone else add on to this with Weasley-twin eclipsing stunts and hijinks, I’m sure there are some but my brain isn’t thinking of them right now.
