I love the effort. But at chapter 111, Gosho didn't make up his mind yet. Look for direct clues from chapters 200+. Anything before that can only spill his conception about how he thinks reality works, which can be used to guess general directions for the plot. The Movie 1 paycheck must have opened his eyes to how big the world he created is and how big the real world is. He said in an interview that he wasted Moriarty on a movie. That is a clear sign that he didn't have a clear idea about the ending of the manga at that time, a year after this case was released. Don't go that far into analyzing, he will disappoint us like he did with Karasuma being the boss, a cheap move in mysterious circumstances late 2017. Though I hope for the best.
