In my opinion, Sanji vs Queen will play out with Sanji whipping out new Rokushoki derived moves, such as the moving Tekkai similar to Jiabra, flying DJ slashes by combining it with Rankyaku, Soru and flying DJ shigun but using his foot instead. He'll also whip out the suit and will do pretty good until Queen uses Haki and awakened hybrid form, where Sanji will be absolutely destroyed, and then he'll awaken his germa genes and gain the exoskeleton and stronger flames after which he'll defeat Queen for good
Zoro's fight will start similarly with Zoro doing pretty good against King but once King uses the advanced Haki and hybrid form he'll destroy Zoro similar to the Mr.1 fight, his Sandai will get broken too but he'll end up defeating King by making Enma into a black blade and defeat him with a one-sword style move
I think Jack will face off against Inu and Neko in Sulong and they'll be sooo close to defeating him but once he awakens he'll mop the floor with both of them and will go on a rampage and for some gag reason he'll follow Usopp around until he beats the living hell of out him and Usopp will think about he needs to man up and start taking serious steps in making his dream into reality, so he'll decide not to play dead and face a rampaging awakened Jack and defeats him using a complex plan and armament haki.
