Oldschool mode for LoL?

I remember back in time, when i played LoL as a newbie. It would be awesome to experience how things were back in season 1, even though things were kinda unbalanced. Might sound like a crazy idea, but i mean Jagex did that to Runescape. Wouldn't it be fun to have an opportunity to play LoL season 1? It could be just an exclusive mode, like URF, Hexakill etc. Have to admit, i do have many good experiences from the beginning of my LoL playing.
