Yeah but if it wraps up the Dragon event AND the Zeref event at the same time then it will run out of material and Mashima would have to go off track. Maybe if he added another timeskip and gave time for more villains to rise then we might have another story but it will ruin the plot line if he adds a character who is stronger than both Zeref and the Dragons besides Natsu. It will be Dragon Ball Z all over again.
