While I'm not disputing the significance of the pseudo-twist that you're underlining here, I do think it could've been executed a bit differently. I remember that the first time I saw the movie in theaters, my mind immediately thought that it was done for the sole purpose of establishing Talia as the main villain to the detriment of Bane. While further analysis of the pseudo-twist in the context of the movie revealed that that wasn't the case at all, I can certainly see why it would come off as such. On first viewings at least.
