Wish we can have a new mode which can let player use champions with old skills

I am a player from season 1, I really hope we can have a new mode maybe called "dream back to Season 2" or something. In that mode, we can use those champion with old skills from years ago, for example: old Soraka. And we can try use same champion with new skills and old skills together against each other. I guess that will be so much fun!! And many old player would like to back to the game and try it.
