Suggestions for Return of the Jedi (part 1)

I read back some pages to see what people suggest, and I think some are way beyond what a good fan edit should be. Some people even want to change the whole movie, but that would not be Return of the Jedi.
So here is what not to do:
Some people already jumping to full scale war in the galaxy, what should have been Star Wars VII.
This movie is not about restoring the Republic. It is about the fall of the Sith and the return of the Jedi, who were all but extinct.
And it is about the Skywalker family, and redemption, and not about the grand scheme of galactic politics and etc…
That was Prequel Trilogy, that explained everything, what we needed to know.
So no full scale war.

Some people think, that the Rebellion grew so much in 6 month, after ESB, that they can take on Coruscant. For gods sake, they tried to take on an unfinished, not yet operational, and a seemingly barely protected Death Star, yet they needed everything they had to do that! So no, they would not consciously take on Coruscant.
People can counter, that they have won. Yeah, but the reason is not that they had a reasonable chance, what happend rather was some unexpected “… adjustments of multiple factors to incline events in one’s favor”.
No battle of Coruscant.

And no two Death Stars please. The first one was completed in like 20 years, now they build 1 and a half in 3 and half years? No way.

Leave the story as it is, and make only subtle changes, that improves the movie, this movie mind you, instead of rewriting it completely. Just as Ady did with ANH and ESB revisited.

Now, about the 6 month gap between ESB and ROTJ. Some people made very valid points about things like:

what the Emperor says to Vader about resuming his search for his son
the plan of Han’s resue is very clumsy
Luke returning to Dagobah only after 6 month

Yes, these feel wrong.
So I was thinking, and now I think, because I know it for a fact, there is no time mentioned in the movie, so this 6 month comes from some place else.
Maybe it was a mistake, and it was 6 weeks, and someone just typed it wrong. It doesn’t matter if it’s Disney canon (crap for business purpose) or not. It is a mistake.
I suggest let’s just accept, that it was only 6 weeks between the 2 movies.
That would fix the unreasonable behaviour of Luke not going back to Yoda for a very long time, and that Vader suspends the most important thing on his mind for 6 months instead of a lot more reasonable 6 weeks. And the 6 weeks theory works for this clumsy rescue plan too.
So there’s no need to rewrite anything, except only one word: "month"
Which is not even in the movie.
