Playing older patches (at least solo or vs bots)

Hello.

It's been i while when new Yorick was released and i was sad about it because i just like old Yorick Mori more. My first thoughts i got after rework was "Will Riot give us, players someday possibility to play older patches" ? I don't mean play vs real players on older patches but only single player or vs bots(something like sandbox mode just older patch). I just want to play true Yorick Mori once again.
