Four initial thoughts
1) Clinton would need to detach from Benghazi as there's going to be an optical problem with what Biden did in Afghanistan ( i.e. an indictment of the Party in general and for establishment Democrats)
The only leverage she really has right now is "her money". Untold sums of previous campaign money and dark money tucked into every corner like Pablo Escobar.
To wipe out two birds with one stone, she's going to have to self fund hiring every high level military contractor she can find and leverage and get them to run ops into Afghanistan to get out American citizens. It needs to be big and splashy. Someone will say Clinton can't do that and can't get away with that, she's not in any kind of office nor in any kind of power position. And I'll say no one can stop her. What are the counter narratives against anyone who tries to stop her?
It would give her a hard reset against her Benghazi narrative.
2) From an aesthetic level, she's going to have to grow her hair out long and lose a tremendous amount of weight. She needs to visually be distinctively different from the 2016 run. She'll also have to divorce Bill Clinton. There are already divorce rumors out there but she needs to strike first. She also going to have to can the fake smile. I understand why she was told that was good media optics and I know of exactly the people hired in private to tell her those things and they are all idiots.
3) Clinton amassed the largest political financial warchest in 2016 that anyone has ever seen. Part of that deal was big money donors expected a return on that investment when she got into office. Well she didn't get into office. So they paid upfront and she didn't deliver. She made a lot of campaign mistakes but she can't rely on that kind of money again. Not even her personal wealth plus all the dark money can cover what this will cost. She needs a "ground game" That means door to doors and young vibrant footsoldiers hitting the pavement. Establishment Democrats don't really maximize a ground game. She didnt' do it in 2016. That means she needs to cut a deal with AOC. She has to carry AOC as her VP candidate and guarantee M4A in public. Anyone who aligns with AOC won't get big hitters from Big Finance to run in lockstep with them. Too much Anti-Semetism in play there with what The Squad has done and said before. What AOC can give Hillary will be a massive social media platform and an entire legion of young zealots. Clinton can't give AOC the entire Green New Deal package, she can drive M4A and put AOC in a better position to run for POTUS on her own down the road. Clinton can't carry Stacey Abrams, two women who previously screamed stolen elections against Trump isn't exactly going to help any Democrat's practical cause.
I don't think Clinton can win in any scenario, but to give herself her best relative shot given the situation, she's going to have to run this lean and with a grind it out mentality. This will be a Dollar Tree version of a Campaign Without Coffers. For a Democrat to win 2024, they have to blend "Republican-Lite" with the less brutal elements of the Progressives.
Clinton made too many enemies and made too many mistakes. She made some brutal ones during the election cycle in 2016 and she made a ton after the election.
4) In order to run against Trump again, she also has to shut down the J6 narrative. Because that's enough to drive away enough support for Trump to push all leverage to either Nikki Haley or Ron DeSantis. She can't beat those two in any format. If she needs Trump cleared from J6 on paper ( but not in legacy), then she needs to pin it on Obama and Biden. She's going to have to trade blows with them anyway trying to take the ticket by force and threatening the ACA. As the FBI are the modern day Praetorian Guard, she's going to have to cut a deal with them as well.
This is pretty ugly. This is like giving Brian Schottenheimer a QB56 like Billy Joe Hobert and expecting to get to the playoffs.
