If there's one thing the Nolan brothers really succeed at with their Batman stories, it's adapting themes and bigger ideas from the comics. They may not be verbatim, but they translate well. For example, the idea of Joker's influence on Harvey up to and especially in the hospital scene is a great adaption of the idea from Killing Joke of the Joker taking one of Batman's allies and driving them mad to prove a point. This in mind, I can definitely see Nolan taking the overall theme from Knightfall of Bruce having to retrain himself to take on Bane again being adapted. At least I hope so.
