Clash of the Universes (Skins) Event!

This idea might be semi-impractical.. BUT.. since skins can technically be obtained for free.. and the skin universes are getting larger.. wouldn't it be pretty cool to have an event that featured "wars" between the different universes?

It could give us a slew of missions, like "win a game with a battlecast champ on your team against a team that has a champ from X, Y, or Z universe"

They could even track interesting stats like the winrates of the universes. Team Pool Party!

Couple of potential issues:

• How would you handle players that choose skins of opposing universes on the same team? Easiest thing would be to just allow it.
• How do you gaurantee everyone can participate? Maybe Riot graces us with a free random skin, of a champ we play, at the start of the event? ;) (one can dream).

Thoughts?
