Well, obviously with an undertaking like this, some things must be compromised. But the cores of the characters are going to be essentially the same.

FADE IN:
EXT. GOTHAM ARENA - NIGHT
Crowds of people flood the city streets. The posters outside read, "TONIGHT ONLY! JACK "THE DEVIL" MURDOCK!" The fight has ended. THOMAS, MARTHA, and BRUCE WAYNE exit the building. They are all extremely well-dressed, and their wealth is obvious. They continue to walk, conversing about the fight. Finally, they turn onto an empty street. A MUGGER approaches them.
MUGGER
Give me your cash!
THOMAS WAYNE
(indignantly)
What?
The mugger pulls out a small revolver. All three Waynes recoil at the sight of it.
MUGGER
Put all the cash and jewelry in the bag!
He throws a pillowcase at them without lowering his gun. Thomas stares at him for a moment.
MARTHA WAYNE
Tom, just do it!
Bruce is speechless. He's too young to understand what's happening. Thomas' face is riddled with disgust, but he obliges.
MUGGER
(points the gun at Bruce)
What about him?
THOMAS WAYNE
He's just a kid!
MUGGER
I want his watch!
MARTHA WAYNE
(pleadingly)
Please...he's a kid!
Without another word, the mugger shoots Martha in the chest. Thomas instantly attacks in response. During the struggle, the gun goes off again. Thomas collapses onto the street. The mugger is suddenly afraid. He runs off into the darkness, leaving Bruce with his dying parents.
BRUCE WAYNE
(with tears in his eyes)
Dad?...Mom?
THOMAS WAYNE
(whispering)
Bruce...be strong, son. Be strong.
