UPCOMING JAIMIENNE OTHELLO AU

So here is the My Fair Warrior outline. The Othello Jaimienne plot bunny has begun to grow for a year. So, what is it? A Jaimienne AU where Jaime turns cloak and leaves for the Stormlands just for the Maid of Tarth... but, what if the past resurfaces, what if their doubts of each other resurface, will the Rains of Castamere plays for them?
The AU will be published either this summer or this winter...

Chapter 0 will be a prologue that opens at Casterly Rock at midnight, with Cersei waking Tywin up because Jaime is unexpectedly missing. There will be a little questioning the Imp, who stays awake reading history and knows nothing... Then, a sealed letter left by Jaime is opened...
CROSS-WESTEROS PERSECUTION ENSUES.
In the end, Brienne and Jaime will meet the Lannisters in the Inn at the Crossroads, where the whole parley will take place and the Lannister heir will be let go, with Tywin's blessing and all (mention of Joanna expected!)...
In this perfectly skippable zeroth chapter, Jaime is Desdemona and Brienne is Othello ("the Maid" instead of "the Moor"). In Chapter I proper, their roles will be flipped. He will be Othello and she will be Desdemona. And Renly will obviously be Cassio. The story proper will switch the setting to Storm's End and Evenfall.

So far, I have cast Jaime, Brienne, Renly, Catelyn or Margaery as Emilia (whom would you pick?), Pod as some kind of Greek chorus, Loras as a Roderigo-Bianca combination, Littlefinger as a candidate for Iago (Oberyn, Arianne, and Roose+Ramsay are also being considered).

So I will have Uttam clear my casting doubts ASAP.
