5. Sabine
Star Wars Rebels has been a huge success, with a comic book and novels already released further fleshing out events between the prequels and original trilogy. It seems inevitable that at least one of the characters from the animated series will be brought to a live-action at some point, and of all the possibilities, Sabine Wren seems like the most interesting. Her age also makes Jones an ideal candidate to play a slightly older version. The character's unique appearance - and particularly that helmet - would make her an easy sell, as would the fact that a lot of moviegoers would already be familiar with her thanks to the cartoon. Marvel are fond of saying that "Everything Is Connected" when it comes to their Cinematic Universe, so Disney taking the same approach with Star Wars makes sense. Seeing what becomes of Sabine gives the cartoon something to build towards too and adds another layer of intrigue as fans will tune in to that to see how she ended up wherever this spin-off takes place. The fact that she's already moving a lot of toys might help too...
