If Disney/Lucasfilm 'cared' so much for the fans and about Chewbacca why has he been relatively sidelined in the sequel films? And why have they killed off both Han and Luke? And why have they turned the original heroes into failures for the most part? Just sounds like Disney taking another swipe at the EU (i.e. old fans). Obviously Lucas himself was selective about what he took from the EU and what he left behind, and further, Clone Wars overwrote some stuff from the EU. Disney could've done the same thing. And Disney is continuing to be selective in re-canonizing EU characters and planets on Rebels. It wouldn't have been much of a stretch to bring over a lot of the EU they liked and been clear about saying we are overwriting Chewbacca's death, which I think some EU fans would've been happy about because Chewbacca's death in the NJO wasn't well-received by some. Further, Disney/Lucasfilm to some extent have mimicked the EU anyway. Rey is similar to Jaina Solo. Kylo Ren is similar to Jacen Solo. I can't think of any ready analogies for Finn and Poe. Poe perhaps takes aspects of Kyp Durron, but for Finn, nothing comes to mind. There might be a more direct inspiration for Poe in the EU but I wasn't a fan of the X-wing series or characters much so I'm likely missing someone.
There is also a New Republic in the EU and there's an Imperial Remnant, the remains of the Galactic Empire. There's even an incredibly powerful dark side user who isn't a Sith like Snoke in Abeloth who was the main villain of The Fate of the Jedi novel series, the last big EU novel series.
What the EU did though was build the Jedi Order, not tear it down. It introduced a lot more Jedi. It also created at least three major enemies besides the Sith. I'm looking at when Del Ray took over the novel line. There were also alien antagonists during the Bantam run but I didn't read those books. For the Del Ray run there was the Yuuzhan Vong, the insectoid Killiks, and Abeloth. There were also other Sith like Lumiya, Caedus, the Lost Tribe of Sith, and the One Sith. I thought there were a lot of cool things in the EU, much cooler than what we've got so far in the sequels and I wish Disney wasn't so hellbent on throwing shade at the EU instead of adapting parts of it.
I think they should adapt:
Thrawn trilogy
Dark Empire
New Jedi Order (Yuuzhan Vong War)
Legacy of the Force
Fate of the Jedi
If they did that they would have movies to last for about 20 or more years, that have more of a cohesive vision than the herky jerky approach Disney is taking now.
