Susanoo needed to be awakened with the owners 2 Mangekyo together, which Obito did not have when he awakened his Mangekyo.. notice how Kakashi had Susanoo the moment he acquired both Mangekyo and unlike Obito he was not nearly spent on chakra. So if Obito was given both of his original Mangekyo he would have his Susanoo, if he only had one of them he would not have Susanoo.
