They already got fired from that. They got hired to make a trilogy before they were done with Game of Thrones. They then rushed to end Game of Thrones early (hbo actually tried to get them to make more seasons but they said no) but then that backfired. After Disney saw how those 2 fucked up the game of thrones ending, the star wars offer was revoked and they were told to fuck offI thought it was because they signed a deal with netflix instead.
