Evidently, you’ve never heard of Saboteur or North by Northwest.
I’m sure there’s some six-issue comic book miniseries devoted solely to exploring this question that I’m unaware of, but couldn’t you just fanwank that away as the Death Star not having been complete, and the Emperor in particular showing up way earlier than the crew had anticipated?
If, after Vader’s visit, their biggest goal was to get the thing working by the time the Emperor got there, they might have been less concerned with building walls to partition off the bottomless pit in the throne room.
I think that in both Cloud City and Death Star II they’re fighting in huge Jeffries Tubes.
Ah, thanks.
Hell, no, not if I were in charge. I’d be having nightmares that ran something like this:
Palpatine: “Excellent, Commander, your recent progress has been most encouraging.”
Me: “Thank you, your majesty. Now, if I may show you to your temporary quarters …”
P: “Temporary quarters? What about my throne room?”
Me: “I apologize, your majesty, but in order to meet your operational requirements, we had to divert some resources. Your throne room is not yet … ack … splutter …”
Darth Vader: “I find your lack of comfortable quarters … disturbing.”
Or Blind Fury.
The Emporer uses the bottomless pit to scare the noobs.
Bottomless? the DeathStar is what, a mile or 2 in diameter?
Over 500 miles actually. But it hardly matters, since the shaft intersects the core. Therefore, any object falling into the shaft (assuming that it isn’t incinerated by the fusion core assembly itself) will continue to fall “up” on the other side until its momentum has been exhausted. So the shaft really is “bottomless,” technically-- it has a top at both ends.
If the fusion generator hadn’t been on line, Palpatine would have continued to fall back and forth through the center of the Death Star until atmospheric friction finally brought him to a halt (or until he realized that he could just use the Force to arrest his fall, the idiot).
Or the darn thing blew up!
Nitpick: it’s actually Fight fight *handectomy * *“I am your father” * “Nooooooo!” plunge to near death
“Handectomy”'s a super-cool term though.
And there are no “tiny points” in the Star Wars saga – esp. in the O.T. 
Er. Well. I meant it was the first science-fiction movie to do it. Of course that’s what I meant.
Well, for all intents and purposes.
Anyway, North by Northwest presents a very unrealistic version of Mount Rushmore in that:
[ul][li]Someone could have a private home and airstrip on top of it, within walking distance of the carved heads[/li][*]Someone could climb down the faces to escape, as opposed to just slipping off Washington’s chin and plunging hundreds of feet to certain death, smashed on the debris from the carving.[/ul]
