Need work on map and please change it in 4 season of the year (Spring, Summer, Fall, and Winter)

This maybe a lame discussion, I'm so tired of those complex mode stuff to get a good map for this Winter (Just enjoy it by myself, sadly :( ) and then I think why don't Riot use or make some Map to celebrate it? Like Thanks Giving Map, or Lunar New Year Map, or Christmas Map, or Halloween Map, or Pool Party Map, or Project Map,..... I can't list all of that here... and I'm kinda tired of New Champ come out every 1-2 months.

You guys can work on those Map and make an incredible Map for those skins (BloodMoon, PROJECT, Zombie and Slayer, Dragon Slayer, Bilgerwater event, etc...)

That may make the players feel more comfortable than nervous waiting and save money for those New skin and Champions. It just my idea. Hope you like it!
