Donkey Kong Silhouette Stage - 0%
I'm going to be a bit absolutist here because I don't think this would ever happen. I say this due to how much development intensive this would be: why in the world would Nintendo waste tons of time and resources creating alternate, silhouetted looks for every character, color palette, alternate costume, attack (including the extra customizable ones), assist trophy, Pokemon, item, and whatever else, all while making sure everything is easily distinguishable from one another, just for the sake of one stage? They can't just change the lighting, they'd have to pretty much rework every element of Smash just to make sure the level is playable, which seems like absolute insanity. Not to say it couldn't make for a good stage, but I can't imagine this ever being attempted.
Want - 50% - I'm torn here: this could be a ridiculous secret stage, yet at the same time it seems like a horrible waste of effort. No doubt the effect is amazing in DKCR, but I'm not sure it makes sense for Smash.
Aran Ryan - 0%
Not much to say here: even if a second Punch-Out!! character were at all likely, I'd have to believe it would be someone far more popular than Aran is.
Want - 0% - No thank you.
