In Planescape, probably more than any other setting, it's the journey that matters much more than actually achieving something in the big picture of things.
The above quote is exactly what I was going to vote for (or explain, since it isn't an option in the poll). Planescape for me has always been about the plane-hopping to new and exotic destinations. There is a reason that Planescape PCs are referred to as "Planewalkers". I suppose that could still be referring to a single plane, but I interpret that as meaning that we're crossing many planes during our adventuring. If a PS mega adventure isn't covering a fairly good number of different planes, then I wouldn't be interested in it. The planes being used also need to differ a lot from each other.
As much as I like them, adventuring on Bytopia, Elysium, Arcadia, & Arborea (or Baator, the Abyss, & Gehenna) one after another would be rather bland. Sure they have their unique traits, but they still will come off as any other non-PS game once you've introduced the quirks of the plane and the players get used to it. The planes used in the adventure need to be much different from one another. Like Bytopia, Limbo, Carceri, Acheron, Astral, & Elemental Air. All completely different environments to keep the players in a state of wonder.
Next, and equally as important to me as the locations being used, is the overall story of the adventure. A mega adventure should involve a more unusual plotline than just rescuing a body or doing a mission for Joe Blow. It should focus more on some sort of planar-like aspect of the setting. Keeping a plane from sliding, dealing with law & order rather than just good & evil, something involving a god or proxie...maybe even dealing with petitioners on a grand scale. I still even like using the McGuffin in my PS games because it can involve that item being used for some planar purpose (or needing to be destroyed by a planar method).
I actually think your poll results are kind of pointless though.
First, "It needs to capture the elusive Planescape *feel*." has the most poll results. That question is obvious though isn't it? But everyone is going to have their own idea about what that "feel" is. I'm not sure how that poll result will help you write a better mega adventure. It's obvious that since so many more people voted for that over the other options, you'll want to cater your adventure with "the PS feel" in mind. But what "feel" is actually important to people so that it "feels" like PS rather than just some fantasy game taking place in some exotic lands? I suggest when you are done with this poll, you create another poll with lots of options to choose from in regards to what the "feel" is for a PS game. Then use those results to help you in your designing of the adventure. For example, some might think having faction stuff is very important to a PS game. Others might not give a darn about factions in a PS game. Some might think you need to use more obscure creatures like slaadi, loths, petitioners, or PS specific monsters. Others might think all the adventure needs is some demons, devils, celestials, and some gods....but that's not necessarily Planescape is it? Others like me, might think you need to actually plane-hop a lot. Some might be perfectly satisfied if they ran the entire adventure in the Abyss. So what do people think is the "feel" for Planescape?
My next gripe about the poll results stems from the, "It needs to be more of a sandbox than a railroad" results. Is this really the 2nd most important thing to people for a great PS mega adventure? First of all, I strongly believe that most people praise sandbox games and bash a railroad game mostly because they feel pressured to do so by the internet. So they want to fit in with popular belief even though that opinion holds little truth.
I've kind of gone off on a rant here and I don't want to derail this thread. So I'm going to elaborate on this sandbox gripe in a new thread.....here.
