Prevent game lost from a summoner DC

I have a new idea that could be useful and prevent loss in the 5 VS 5 Summoner Rift game.

My idea is when a summoner DC then a BOT should take its place with the same champ and same items the player has bought and replace him if he doesn't come back in 2 mins. This should prevent a one way game loss.

Because most of the time I faced it that we are winning the game and suddenly someone DC, the game then turns when the enemy team knows it and they starts team fights in group and we lose :(

This idea seems to be useful and a better way to prevent from such situations where the team lost because of a DC player.

Thanks!
