Big Daddy and Hit Girl vs The Dark Knight Rises

Bane has control of Gotham. Batman is in the Pit, the cops are imprisoned underground, and insane criminals control the law. Big Daddy and Hit Girl get 24 hours prep, and then they infiltrate with as much gear and equipment as they can carry. They know they have to find the nuke and that Lucius can disarm it, and the police are trapped underground. Can they save the day and take down Bane and the League of Shadows?

They kill Bane easily enough but i think Talia would blow the bomb before they got to it.

Like above, I doubt they could stop the bomb in time.
