I completely support your suggestion, in fact I made a similar one asking season changes in-game a long time ago but was quickly forgotten and probably never seen by the Devs, I hope they can see it this time!...
@
SE and anyone else interested
Have you ever played
Pokémon Black &
Pokémon White!?... You definitely should as they show how seasons can work inside a game by cycling them every single month of real life time, even special fiends could appear during specific seasons not to mention quests and whatnot, it would make the game all the better!...
Forget about excuses and let the
Producer and the Dev Team make it a reality, regardless of how poor the game code is they can absolutely make it!...
