Now I understand that's why you wouldn't use the orphanage at all, but it plays a part in the fact that Bruce and Blake are both orphans and the last thing Bruce helps his city with his helping out the orphans in the end.
I wouldn't just give up Wayne Manor to orphanage in the end is all, and cut a 2 minute scene where Blake visits.
Though I can see your point about Alfred joining Bruce at the end, maybe a simple smile and nod is all we need and then the viewer can decide what happens next. Though I still like Alfred tracking down the pearls as a better method for the ending sequence.
