Add extra content to Summoner's Rift? (NA)

I Don't mean to sound like "Changing" the Map: 'Summoner Rift' around, but I mean to as in like add Seasonal Map. Like for example: Making Summoner Rift map look somewhat like the Autumn/Fall, Winter, and Spring. Maybe add Thanksgiving as well? Christmas? St. Patrick's Day? Riot (or Rito for some of you guys who calls it that way) Should add some of the Seasonal content to the Map. It's just coming from me. Not sure if anyone else will Agree, but that's just me.
