Personally, I don't like the idea of making Bryson and Katz into a couple of gray haired geezers. Just cast it as it was written if you're going to do it. Kind of like making a James Bond movie, but casting a 5' tall 350 lb sumo wrestler as Bond and then saying "It'll be just like the books, only different!"
