Nice breakdown. I find it very interesting that the Vinsmoke side of things is completely based on how well the operation is executed. Reiju will probably only speak up on Big Mom's intentions if things unfold in a way where it becomes obvious that Sanji is trying to save them. If Luffy jumps the gun and they end up being seen as a hinderance to their affairs, Reiju trying to speak up won't hold as much water.

Also, while we haven't been given an explanation, I'm willing to bet that Katakuri's Obseravation Haki still requires focus. He didn't just randomly have some kind of premonition of Jigra's intentions, but rather decided to observe Jigra first after seeing how rowdy he was, and THEN had a vision after watching his behavior. I think we'll only have to worry about his haki if he happens to be watching Bege, Big Mom, or Pudding/Sanji, but he can't focus on all three of these at once. Hopefully Bege can execute his part while Katakuri has his hands tied with Big Mom, but we'll see.
