The recently released Marvel comics Star Wars #108 was a continuation of Legends material, so its not impossible. But since they’re making new movies that can’t connect to Legends they’re focusing on new tie-in stories in stead. They most likely know that they could make money by continuing Legends, but focusing on a new audience rater than catering to the old and making stories that connects with the new movies is probably (I would assume) the most profitable thing to do at the moment.
