New Game Mode

So some of you might remember a game mode in DoTa where you would chose a champion in game, rush out to fight mobs and AI champs, and try to level and grind until 15-20 min. At that point the boss monster at the top of the map would start making his way down the map to your nexus. You had a set amount of time to kill him before he finally made his way to your base. If you didn't kill him before that, he would start beating on your base until eventually you lost. I would love to see this game made here on League. The boss monster would have to be baron. Not the "clone" baron that we have on SR, but the REAL BARON NASHOR. Thoughts?
