Leauge of Legends Zombie mode

I think it would be cool if they created a zombie mode that had 2 teams defending a nexus against swarms of invading Minions Which starts easy and they further alone it goes more minions / stronger minions spawn. If possible have a couple boss level spawns with dragons. All the while this is a 5v5 game with both teams of 5 defending their nexus, at any point the enemy can leave their base and attack the other of course leaving their base less protected. The winners are the team whos nexus doesnt get destroyed. Just a different take on the game and would be cool. I call it Zombie mode. What do you guys think?
