Loyalty is also a big theme. Harry has to build a loyal crew around her in the mafia world. There are often sub - plots about who she can trust, who will betray her, and how she deals with traitors. This adds a lot of drama and tension to the stories.
Another theme is secrecy. Harry usually has to keep her double life as a mafia boss and a wizard (if it's set in the HP universe) a secret. So, there's a lot of sneaking around and hiding her true identity from different parties.
Power is a common theme. Harry, as a mafia boss, is often depicted as seeking and wielding power in different ways compared to the original series. Another theme is loyalty, as in the mafia world, loyalty to the boss and the group is crucial.
One of the main themes is survival. In the cut - throat world of the mafia, the female mafia boss has to constantly fight to survive. This includes dealing with rival gangs, double - crossing allies, and avoiding the law. Also, leadership is a big theme. She has to lead her men, make tough choices, and inspire fear and respect. There's also the theme of secrecy, as she has to keep her operations hidden from the outside world.
Common themes include conflict. There will be conflict between the values of the mafia, like violence and control, and the values of the wizarding world such as justice and equality. Redemption can also be a theme, where perhaps the mafia boss has a chance to change his ways in the magical context. Additionally, there is often the theme of discovery, like the mafia boss discovering the existence of magic or a wizard finding out about the mafia underworld.
A common theme is danger. With Edward being a mafia boss, there's always a sense of threat looming. Another is forbidden love. Bella getting involved with someone in the mafia world is often seen as something society or her family might not approve of.

One could imagine that a distant relative of the Black family, who has been disgraced or cast out, becomes a mafia boss. They still have some of the Black family's wealth and dark magic knowledge, but use it in a more criminal way. For example, they could be running a protection racket in Knockturn Alley, threatening shop owners to pay up or face dark magic. Severus Snape also could potentially be a mafia boss in an alternate story. He has the intelligence and the ability to be secretive. He could be using his potions expertise to create and sell illegal or dangerous potions on the black market, while also maintaining a network of spies and henchmen within Hogwarts and the wizarding world.
One common plot could be power struggles. Harry Potter, as the mafia boss, might be constantly fighting other powerful wizards or groups who want to take over his 'territory' in the wizarding underworld. Another plot could be about revenge. Maybe someone from his past in the wizarding world wronged him, and now he's using his mafia - like power to get back at them.
