Make Old Seasons/Map A Game Mode

So I recently started playing this February and Now LoL is my life xD, after watching so so so many videos from the past seasons I think itd be cool to have the summoners rift and items from previous seasons available as a game mode. S4 looks so much more fun especially for junglers and it seemed like there were a lot more strategies and buildpaths and starts and I would really like the chance to experience the old league of legends and everything it has to offer. Also long term players could enjoy doing their favorite things before meta changes and you could play it if you feel nostalgic. One thing I really want to do is the old trick2g thing where you get a feral flare and a spirit stone and also a lot more champs could solo the barron. Idk s4 looks so fun and I think making it available would be all around really nice.
