Demacia vs Noxus game mode & map

How about creating a game mode in which you have to choose to be on the side of Demacia or Noxus (mabye some more factions). After choosing your side you can only pick a champ that is a member of the chosen faction. This way you'll get an epic battle between, for example, Demacia and Noxus.

Tips:

• In champ select for Demacia use the themesong: Demacia rising. This to create an intense vibe and insentive to fight for that faction.
• Chance the summoners rift:
  - a tipically Noxus side, Purple becomes red and dark. Give turrets, structures and the landscape a more Noxian visualization. - a tipically Demacia side, blue becomes gold and light. Give turrets, structures and the landscape a more Demacian visualization.

Create and epic battle between good and evil and try finding fitting music for this map, mabye the recently created music.
