I think it would be very cool, if Fujin's actions on Sunagakure were such, that Orochimaru would feel more certain about his cooperation with the Kazekage, to the point that he does not feel like betraying them prematurely. Firstly, I do not think Orochimaru would be as dumb, as to face so many active foes, without any allies, the Hokage alone would already be quite dangerous for him, and if you add Fujin, I do not think Orochimaru would dare to take the two alone. Secondly, is because I think Orochimaru would be certain that his allies would not betray him. We really do not know on Canon what was the explanation of why Orochimaru killed them, but one that would not really contradict any of the Canon, and would fit very nicely with this fanfic, would be that he killed them, because the Kazekage was backing out, both because he was not certain that Konoha were the responsible ones behind the attack, and because he was fearful of them. Perhaps Orochimaru suspected that the Kazekage would betray him, and would ally with Konoha once more to plan a double-betrayal against him, which is why he murdered him preventively. However, on this timeline after being struck time and time again by Fujin, perhaps this time he would be far more hateful towards Konoha and would be willing to disregard everything to face them off. With this, there could be a Konoha crush arc, where both Orochimaru and the Kazekage cooperate together to destroy Konoha. Not only this would be cool to see, but it would also allow for the Kazekage to face directly Fujin. Obviously, the Kazekage would head out towards him, both due to the hatred he feels towards him, as well as to confirm if he was the culprit behind the many disasters that befell on his Village. With that, it could begin an interesting arc, where Fujin faces a powerful Kage, and fully shows himself to be worthy of the title of 'Wind Calamity.'
