You people are too quick to lay down any plan before you ever discuss what constitutes neutral/counterpick/banned stages.
----------------------------------------------------------
Here you go:
Neutral: are just that, neutral. They don't have explosions, they don't have big fish eating you, they don't have weird gravitational effects or dancing ******* flinging poo at you. Think: Battlefield and Final Destination.
Counterpick: These are as close to neutral as you can get without being neutral. There are explosions, there are stage changes, there are the occasional dancing ******* flinging their feces at you. The idea behind it is the player has practiced enough of this level to give him an advantage against his opponent. When the stage hazards can be abused is when it is...
BANNED!: These stages are perfect to abuse and make for a terrible match for those players smart enough to take advantage of. This will always include:
- Walls (trapping a player against a wall for 30 seconds is no fun to watch)
- Walk-offs (shining/chain-throwing/etc until they're dead is an obvious abuse)
- Fall-throughs (falling through a stage is almost a guaranteed loss of stock and unfair advantage, johnning about it is understandable).

Everyone wants a clean fight, in a competitive tournament scene this limits the players to just the neutral stages and a few counterpicks to choose from. It's not your friend's living room, this is money people are competing for, it's about the SKILL of the players competing.
Now that you have something to work with, you'll find this a lot easier to figure out.
Just so you know, we competitive players already have our determined list of stages, so I don't see what the point of this would be.
