The only way an animated version would work is if it was at the level of Akira or Ghost In the Shell in quality. I don't mean anime in terms of style. Not all all. I mean the painstaking details and beauty and world-building that went into those productions. Akira was very close to the art style of Katsuhiro Otomo and showed that any story could work in animation. Stylized won't work like with Clone wars and Rebels because Star Wars is a visual experience. The stories are simpler (I'm being kind) and the characters don't monologue. Star Trek is talking heads with a side of action and adventure.
