You've put some real time into preparing for them. I'm impressed. And very entertaining.
If you are interested, check out the changes to the D&C.
It was originally the Book of Commandments. It had some sections of it highly altered over the years. Another instance of the words of god changing after they were already written down.
Multiple editions can be found on the LDS web site.http://josephsmithpapers.org/the-papers#/R2L/JSPPR2
Maybe compare BoC section 4 to D&C section 5.
It might start from a question like, "What are these other scripture that you carry? Just the BoM?"
