Easy, we'll just give the manager a cut.

I wouldn’t be so sure that adults is enough to stop grifters as grifters are adults too, they have different goals and quite often they reach them.

One of them just needs to become the manager.

You're going to need another person to become the HR rep that gets your case assigned, too, and probably that rep's manager/whomever handles appeals, as well as the manager & HR rep dealing with the cases that any concerned co-workers will raise, as well as everyone else who was involved that established a company-spanning pattern of harassment that nobody did anything about.

An absolutely trivial conspiracy to pull off, especially given that the median payout for this is closer to ~zero dollars, and most likely, a ruined career for everyone involved, and federal prison time, if any of this is sussed out. Maybe the Donald will give you a pardon once he returns to the presidency, on July 4th, 2023, or whenever.

Feel free to give it a shot, and let us know how it turns out. Meanwhile, I'm a bit busy conspiring with my buddy to become the CEO and the CFO of Tesla, respectively, so that we can take all it's money and fly to the Bahamas.
