So it's quite possible the outlines Lucas made for the third trilogy could be very old, going back to the 1970s.
Those were very rough outlines as I recall.
At the time that there were nine movies (Empire Strikes Back
would have already been in production) the middle three chapters were the only ones that actually conformed to a trilogy. Episodes I and II jumped dozens of hundreds of years forward in time (creation of the Republic, that sort of thing), leaving III to cover what eventually became the prequel trilogy. Then I think in films VII-VIII Luke finally confronts his sister (not Leia) and the Emperor... then IX would have been a distant coda/episode film of sorts... my recollection is quite sketchy. Lucas' so-called master plan changed with every film that was in production.
