I wrote a Fighter revision that might interest you.
It isn't exactly what you're asking for, because this homebrew does not have Battle Master maneuvers. But it does have reliable attacks, reliable saves, and a choice of not one but two subclasses. Your first subclass, your Fighting Style, grants you new actions and attacks in combat (which, unlike maneuvers, you can use as much as you want). Your second subclass, your Line of Duty, grants utility features meant to help you in and out of combat alike.
The only think you want that I did not include is Second Wind. Instead of making mid-combat healing available to all Fighters, I made it exclusive to the Guardian (who can basically give himself temporary hit points at will and use them to protect other people), and the Medic (who can heal anyone he touches once per the target's rest).
