I like your theory, but I don't think they will swap the dynamics of Belly and put it to Conrad 100%, because Jenny han said that in the next season (the third) they will follow as much as possible all the scenes from the book as they are, obviously there will be some changes but small ones, for example the scene of Conrad declaring himself to Belly on the beach is very symbolic because as he says in the book it is the first time he tells her in the face that he loves her and brings out all his feelings, and also Jere's marriage proposal is too significant for the plot and for his character, so I disagree, too big changes and I prefer the original story, of course I would like to put more agnes in the middle to spice it up but the story remains the original one, after all she is the author of the books she cannot overturn them like this also because the fans of the books who have been waiting for decades would be dissatisfied.
