 * Wrecking Crew: Banned (Too Big, Barrels)
 * Orbital Gate Assault: Banned (Arwing Lasers, Some Parts Too Big, plus most stages that move across several platforms like this are banned)

The following stages you said will be legal will likely be banned:
 * Mario Circuit (SSBWU): Racers, some parts have walk off edges
 * Pilot Wings: Tilting greatly affects usage of projectiles
 * Skyloft: Some parts have walk off edges
 * Wuhu Island: Some parts have walk off edges
 * Yoshi's Woolly World: Too big, walk off edges
 * Castle Siege: Too big, walk off edges in second form
 * Congo Jungle: Barrel cannons
 * Delfino Plaza: Some parts have walk off edges
 * Halberd: Combo Cannon
 * Luigi's Mansion: Too big
 * Lylat Cruise: Tilting greatly affects projectile usage
 * Pokemon Stadium 2: Different forms affect gameplay too much (example: slippery floor in the ice form)

Also you should separate it into Singles and Doubles since some of these are probably banned for singles but legal for doubles.
