Hmm. Mattie's father as a trickster? That's a little tricky for me to wrap my mind around.
I subscribe to your list of character archetypes, Scott, but I just don't see how her father plays that role.
Number one: he is killed in the opening scene. He's a past presence in the story, not a present one, actively raising trouble, upsetting the status quo.
Number two: A trickster character is by nature and deliberate purpose an anarchist, a capricious rule breaker, someone who makes trouble for the sheer sake of making trouble, some who by temperament or willful intention defies normative conventions, breaks the rules, upsets the status.
What little we know about Mattie's father suggests he's none of the above. That he upset her status quo was involuntary, that he hired the wrong guy was unintentional.
If I am compelled to fill the role of trickster for this film, my candidate is the Wild West -- the lawless milieu in which Mattie must pursue her father's killer. She lives on the edge of the frontier where the law is capriciously observed and enforced.
We get a clue of this in the opening scene where in her V.O., Mattie notes that no one bothered to pursue Chaney, murder being so common in that time and place. And we get another clue at the hanging, when the Indian doesn't get his fair chance to say his final words.
And then there's Rooster's court testimony which clearly reveals he's not one to adhere to rules of engagement. Nor does he have to in order to bring outlaws to "frontier justice".
When Mattie asks the sheriff to recommend a marshal to hire, she rejects Quinn, who is fair, who brings his man in alive, for Rooster because he's the meanest and the most fearless. He's the marshal best suited to achieving her objective goal in the trickster environment of the Wild West.
