Shannon & Boone on LOST again?

Maggie Grace told E! News of Lost “I’m looking forward to visiting Hawaii soon. I don’t know why…” Grace played Shannon on the show, and I loved her. And I loved Shannon’s brother, Boone, even more. Is there a chance Ian Somerhalder would be back? I have a feeling he would for sure, if he wasn’t already on another series (The Vampire Diaries). However! He told TV Guide Magazine that, “I’ve heard a little bit about what’s happening this season on Lost, and there’s definitely an avenue they’re going down to bring back a lot of us. Any crossover [with] Lost would only help the success of our show… as long as it’s not screwing up production.” Sounds like he’d love to do it. And how does Somerhalder know spoilers about Lost when the Lost cast claims they know nothing? Rawr.
