No, because that would ruin The Joker's fun. Which in part is having this "over" Bruce that he could reveal it at any moment.
The book was very good, I agree. I sort-of thought maybe the faces would be removed but at the end :technobabble: and the faces would be back on with no problem. (A flip-through of Batgirl showed her with her face, but bandaged slightly.)
But I thought the book was a very good ending to the arc, the story and the art in Batman has pretty much consistently been fantastic.
