A "new" game mode

Today I was playing a match and as i usually do i went to look at some YouTube videos. When i was looking at the videos it hit me like a brick. When the new map came out I was in love with it and it was the best, but now i don't feel that anymore. I am not saying that I don't like the new map but it's just.... an example of what I am trying to say is: When a little boy begs you for this one toy and he just keeps on annoying you for that single toy until the day you just give in and get him the toy. The boy will only stay happy for like 3 to 5 days happy with that toy, afterwards he will just get bored of it and leave it aside and then you see that he didn't really want that toy after. In other words it was like a itch that he just had to scratch. And now to what i wanted to say.. Riot can we get a "new" game mode. A mode where we can again experience the old map and the old jungle with all the old champion art and outdated skins. If that is not possible then okay, i tried. But please answer me the question, was this suggestion ever a possibility?
