Champion growth concept...

Not to take away from the core elements of league of legends but. the league universe is constantly growing and constantly being developed and changed not to mention there are characters with evolving storylines coming into play. so the thought literally just came to me that suppose for certain champions eg. annie what if there was an option to play annie as an adult with a different kit. so there would be 2 annies in league of legends that a player could choose from annie v1 the child or annie v2 the adult. league is a video game and the playerbase loves their character but the universe is constantly moving forward. so what is champions could reflect that growth. another eg is garen. say hypothetically demacia fell and their acts of subjugation against mages came to light and garen not knowing what to have faith undergoes a transformation psychologically he wouldnt be the same garen so wouldnt there have to be a change in hit kit to reflect that. this is all just a random though and I hope someone can atleast tell me it's a possibility or theres no way it could ever work based on the direction riot wants to take.
