I'd add something like spinning barrels on the sides, and you can hop into those barrels and use them to throw yourself as a high-knockback projectile towards your enemies...but you've got to admit that filtering sunlight would make the stage an amazing experience just with that.
That would make it less likely to see use as a tournament stage which, while entirely irrelevant to its quality, would give it a lot less use than it deserved. Alternatively, how about side on rotating barrels that drop you off the stage if you don't keep moving or jump off?
Whatever the case though, I would definitely play it just for the sunlight effect.
