It'd be awesome. Not for competitive matches mind you, but for local multiplayer? The more chaotic the better IMO :P
The Wii U already supports 5 controllers at once (4 Pro, Classic, or Wiimotes, and 1 GamePad), if they could just find a way that allows the GCN controller adapter to register those controllers as 6-8 (or 5-8 if someone doesn't want to use the GamePad) and boom. You have 8 controllers ready to go.
Bets:
1. If the Wii U sells closer to 10 million LTD by 1/3/2015 I win. If it sells closer to 9.5 million LTD by 1/3/2015 OfficerRaichu15 wins (winner gets 2 weeks of avatar control)--Lost.
