"This year's 38th issue of Shueisha's Weekly Shonen Jump magazine revealed on Monday that Nisekoi manga creator Naoshi Komi will draw a "cover chapter" for Eiichiro Oda's One Piece manga. The "VIvi no Bōken" (Vivi's Adventure) chapter will be the latest in an ongoing "Cover Comic Project" for One Piece, and Shueisha will publish the chapter in the magazine's 39th issue on August 31.
Komi's "Vivi no Bōken" (Vivi's Adventure) cover chapter will be from the Alabasta arc, and will cover "that famous scene" after the long fight is over. The chapter will be 48 pages long including a color page."
He also cites One Piece as one of his biggest influences, so I am sure he is happy about that.
