They did. Dune 7 come out as Hunters of Dune in 2006. It's ... ok. (No, it's really not, but no point in dwelling on it. It's just not the same Dune. Frank wrote each book because he had very specific ideas, experiences, concepts, thoughts, problems in his mind. Brian wrote it to "finish" the saga. I very much recommend this amazing talk about the context of the original books: https://www.youtube.com/watch?v=AWDCgKdmly4 https://www.youtube.com/watch?v=AWDCgKdmly4 ... and I think there's simply no point in "finishing" Dune, because it's like StarWars or StarTrek, there's no end to it. Just as there's always a new/old/forgotten/prodigal Skywalker, there's always an Atreides somewhere :))
