Another plot could be that they travel to a time in the future where Pokémon have evolved in unexpected ways. They then have to adapt quickly to this new world and find a way to get back to their own time. Maybe they meet future versions of themselves who are very different due to the changed circumstances in that future world.
One idea could be that Ash and Serena travel back to the beginning of Ash's Pokémon journey. They could use their knowledge of future events to help Ash catch even more powerful Pokémon right from the start. For example, they might know where to find a rare Pikachu variant and help Ash catch it, changing the whole dynamic of his early battles.
