One interesting story could be about Ash's journey in the Kalos region in a more in - depth way. For example, his encounters with different Pokemon and trainers that weren't fully explored in the anime. Another might focus on his relationship with his Pokemon in a new light, like how he trains them specifically for Kalos - style battles.
One exciting plotline could be Ash encountering a new and extremely powerful Pokemon that he has to figure out how to catch. Maybe it has unique abilities that no one has ever seen before.
