Mitch, I’m pretty sure you are talking about expanded universe stuff and I doubt Lucas would adapt other people’s work when he could just come up with his own stories. Expect fail.
You be surprised, actually. The Thrawn Crisis is considered canonical, as are many of the trilogy novels that take place after RotJ. Now there’s a point where the canon stops but I think it’s pretty well established up to around 100 years after RotJ.
Now granted, canonical doesn’t implicitly mean Lucas-approved but if he plans on re-writing the series’ canon he’ll create a massive exodus of fans in the process.
