The Dupains (B-Team rewrite post)
TLDR; I will talk about both Tom and Sabines sides of the family, but this post mostly focuses on the Dupains. Also, Marc, his parents and Fei are apart of the family too. Marc is now Marinettes biological cousin, and Fei is her adopted cousin

LORE
To start things off, while Roland and Gina were married they had two children, Tom and Nina (Mrs Anciel). Tom followed in his fathers footsteps and became a baker, while Nina pursued meteorology and became TVi's weather reporter. Roland and Gina later divorced after their kids grew up, and the family went no-contact with him following Tom's wedding. (I believe the fandom consensus is that he didn't attend the wedding because he disproved of Sabine, since he's very old-fashioned and racist)
In this rewrite, the wedding picture would also depict Nina and her husband Emmanuel (Mr Anciel), who she later took his last name
Sabine grew up in Shanghai with her parents Mei and Yan Cheng, her uncle Wang Cheng, and her twin sister Shu Yin. By this time, the Order of the Guardians have been disbanded (see my Lila post here for the lore)
In case you don't want to read that post; the rewritten Order is separated into Mages and Guardians. Mages are descendants of the original creator of the Miraculous, given power by Gimmie. They can read Grimoires naturally and can create other jewels. Guardians on the other hand must undergo a ritual to read Miraculous texts, and that's all they can do. The actual ritual is lost, but descendants of the Guardians still get self-defense training. After finishing hers, Sabine traveled to Paris for new career opportunities, meeting Tom
I bring up the Shanghai special, since the Prodigious's role in the story is significantly changed. The pendant exists as a result of the hubris of the Guardians who tried making their own Miraculous w/out the blessing of GImmie, instead creating something very dangerous and limited
In saying all that, a trip to Shanghai to visit her maternal grandparents is the perfect opportunity to bring the World special into the plot, and makes much more sense than Marinette chasing Adrien over international boarders
Since Ladybug randomly shows up in Shanghai on their trip, alongside her daughters absence, this is where Sabine starts putting two-in-two together that her daughters a superhero. She isn't 100% certain, but she supports her daughter from the sidelines
As far as Fei goes, who I believe gets adopted by Wang Cheng uncle by the end; her story remains relatively unchanged; with the exceptions that she robs Marinette on a family trip, and that she starts undergoing Guardian training to wield the Prodigious safely. She, Marinette and Marc - though she's not as close to him - all consider eachother family and face-time regularly
Anyways, after Tom and Sabines wedding, they had Marinette, and around this time Nina and Emmanuel also had Marc
In this rewrite, since Marc and Marinette are cousins who live in close proximity to each-other, they are pretty close, though they orbit different friend groups. Marinette had Nino and Socqueline, while Marc had Alix. During the height of Chloe's bullying, Marc was one of the only other one of her classmates willing to associate with Marinette (alongside Nino obviously). Both of them are clumsy, socially awkward misfits
Marc in this instance also probably knows about Fei's superhero identity as LAdy Dragon, and it's an open secret within the family
As far as every-bodies akumatisations are concerned, they remain mostly unchanged (Simpleman will not exist), except Befana takes up Riginarazoines power. Obviously Nina and Emmanuel need new villain concepts since they're basically OC's at this point, so I'm calling them Solar Flare and Party Crasher, for I do not care enough about Wayhem
Happening around Season 2 or 3, Nina is giving a report on an upcoming heatwave, something about it starts her global warming anxiety, which Monarch capitalises on, turning her into Solar Flare (shown as Smolderdash from Skylanders). Her power lets her absorb heat and sunlight, turning them into fire and laser beams. Potions are unlocked by now, the Red Potion gets revealed as her direct counter, protecting the user from fire, lava and heat
Party Crasher on the other hand at least happens after Evilistrator and Reverser, whenever Marc and Nathaniel start their comic together. Emmanuel is worried about people making fun of their "comic", an allegory for their relationship, and so channels all his 1970's flamboyance into his akumatised form, always one step ahead from uncertainty (his powers are the same, as in the show)
Because of my different plot structure (there's a time-skip between seasons 3-4 where Lila obtains the Peacock), Dearest Family changes from being a bunch of akumatised people, probably into a giant tree sentimonster called Dearest Family. Marc ends up getting willingly akumatised by Fritilary (Master Fu using the Butterfly Miraculous) in order to give his family a different perspective
EDIT: I heard Mr Anciel's name is Emmanuel and he's based on a line producer? And he owns a bookstore in Dirtfiers. I will be translating both of these into the rewrite
This might sound really weird, and I don't think I had ever mentioned this to anyone, but I had a really similar theory about Marc's mother to this.
It was that Tom had an older twin sister named Nini and I had never really thought about her job but this has made me go insane.
