How? How would it work? You can't possibly have a game with 800+ individual characters with the amount of unique animations you'd need to make it fun and balanced. By then you'd have a completely different game. Or like ya know... Pokken.
Can the RPG mechanics in Pokemon be improved? Yes. Of course. But its roots should remain in being a turn-based RPG.
