SPECULATION With R1's release, what further references would you like to see in VIII and/or IX?

Ok folks, now that we've seen Rogue One and TFA, what FURTHER things would you like to see even more now in the upcoming films? How has this film changed your vision for future films?

Personally, Vader's castle is as mysterious and terrifying as it is interesting, and now that Vader is dead...what becomes of it? Since Disney bought LFL and revived SW, and after having seen TFA, I've always wanted to see what remains of the Jedi Temple on Coruscant....and now Vader's castle on Mustafar...and I'd love to SEE Luke at both locations, not just read about it in a novel.

Also, Vanessa Marshall today announced that Dave Filoni has confirmed that "General Syndulla" called out in R1 is IN FACT Hera from Rebels as we suspected when the Ghost and Chopper both made screen cameo's. With that being said, it's pretty safe to say that Hera survives into the OT timeline, and potentially beyond....show me an older, aged Hera...give her lines...show me, I dare you!

As we all know, this saga is about the Force and the Skywalker family line, but I'd love to see these things portrayed in the new storyline as a sort of "help" to the new (and old) cast...to "Let me tell you a story" type of appearance somewhat like Lor San Tekka in TFA....only provide a story to Luke and the kids as a guide on their journey.

Thoughts?
