Yeah, I think Ghost Yoda taught Luke the Force Ghost technique between 6 and 7. But yeah, it would be cool to see them both. Episode 8 proved Ghost Yoda can be entertaining and meaningful, imo. I'd think Liam Neeson is game to reprise the role. I seem to recall back in January he said he was open to it.Oh I don't think you were completely wrong. As we really don't know exactly how this training was conducted. Was Luke ever trained in Episodes 4 through 6? No. So, IMHO, I feel like there's gonna be some retconning. I'm excited to see if they give us both Yoda and Qui-Gon in this film.
