Mark Hamil has had a long voice acting career and I don't think he'd mind returning to be Luke Skywalker one more time at least. He seems to really care what his fans think of him.
He resents Star Wars these days, and apparently has a secret bitterness towards Ford.
"Well you know - there was some jealousy I think - um, you know I have to be incredibly careful... Harrison had this enormous career - what was it, by the second one or third one? And I think that was tough for Mark. "I'm the one who - it's adventures of Luke Skywalker! How did - this wasn't supposed to happen."" -Carrie Fisher on "Bring Back: Star Wars"
Carrie Fischer is Bat **** crazy these days so I don't see (or want) her to return.
She's not crazy, she's just hilarious. She's a natural comedian, so when people see her goofing around it makes them go "WTF
"
Harrison Ford wanted Han to die in Jedi, he felt his character really had nothing more to learn or do, that he was pretty one dimensional and that the best thing he could do is die. So I'm 99% sure he's not coming back.
What if he dies in Ep VII?
Anthony Daniels and Kenny Baker seems to be willing to return for anything.
Anthony Daniels hates Kenny Baker. He cancels appearances to events when he finds out Baker will be present. Either way, I'm sure they wouldn't use Baker anymore as he's pretty old, and Daniels would definitely not be on set. He's a pretentious dick. He'd probably just do the voice overs, with the Voice Directing Assistant pampering him in ADR.
Hayden Christensen is pretty type cast as Anakin Skywalker, I haven't seen him in much since Jumper. He'd probably return though just because he hasn't been in much and he seemed to love playing Darth Vader.
Unless they used a Sebastian Shaw look-a-like, a LOT of fans would be pissed off. Technically speaking, Anakin's ghost in canon is older. The Christensen version is simply the 2004 and beyond special edition version. You'd need someone like Michael Gambon in a wig to pull him off. He looks a lot like Shaw did, and he's a phenomenal actor.
Ewan McGreggor took his role of Obi-Wan very seriously and did a very good job impersonating Sir Alec Guiness while bringing something of his own to the role. He seemed generally pleased with the role and I think he'd be willing to return.
If they did their makeup magic, this would be the only prequel actor I'd be down with them bringing back.
Natalie Portman pretty much just phoned the whole thing in and her career has blown up since Star Wars has ended, I doubt she'd be willing to return, even if there was some way that she could.
Padme has no place in the ST. There was one instance in one of the books where R2 plays a holo recording of Anakin and Padme talking, but they could easily just used archival footage from ROTS.
Liam Neison wanted to return for Revenger of the Sith but couldn't do to his motorcycle accident. Funny he was also featured as a mentor in the first installment only to return as a vision in the third in his role in the Nolan Batman films. Anyway that being said I think he would return
Like Padme, Qui-Gon has no place in a new trilogy. He never actually became one with the Force. He found the route and communicated it to Yoda. Obi-Wan was the first to do it. (As far as I'm concerned, EU isn't canon).
Furthermore, Liam Neeson said he only did TPM to have Lucas on his resume. He doesn't care for the films and hated his experience on set. Him not returning for a V.O. in ROTS had nothing to do with his accident. He came out and said he didn't care for it. He didn't even do it for AOTC when you hear (what sounds like Qui-Gon) yell "Anakin! No!" during Yoda's meditation (also serving as a precursor to Yoda's communications with him in ROTS). There was supposed to be more to it than just that, but he refused to return. Although it's supposed to be Qui-Gon, they claimed that the actor voicing that scene is a recast, even though him yelling "Anakin!" is the exact same yell that Qui-Gon cries in TPM when Maul is about to hit him with his speeder bike on Tatooine. The "Noo!!" is definitely not Neeson.
Anyways, Lucasfilms got away with this without having to pay Neeson a penny and Neeson has publicly said he wouldn't do another one.
I don't necessarily want all of these people to return I'm just saying who I think would and would not.
I'm actually curious how you came to these conclusions...
I think most importantly though, we should have Frank Oz return, Yoda as a practical muppet with CG overlay.

) but I agree the authenticity of the sequel is reduced if there are hardly any links to the older films.
