I agree with it entirely, we need something radical to shake things up. On the point of relying on others, we'd be relying on every other team rather than just one or two, so might not be that risky. Aint done the maths though.
The key in boosting attendances is away fans I'd say, and equal gate splits would be the best way to encourage that. Clubs would be more inclined to run busses and encourage fans to get to away games aswell as home.
