User blog comment:OnePieceNation/Which of these series wouldn't you mind getting a crossover with Hunter X Hunter/@comment-9096809-20130701204533/@comment-4783583-20130701223732

Opinions are never meaningless, only through taking the time to hear someone else his/her opinion can people try to get along and work together. Everybody thinks differently about things and as long as you stay civil and calm you can have a dialogue or debate about anything and everything.

Back on topic I have never seen a complete crossover arc, but it might indeed be really badass is a series dicides to do one. Though if one does an arc, it might actually be a canon one, like there are a lot of canon crossovers in comic books.
