- Angron was a moot point due to the implants in his head. He probably would have died before the "great crusade" truly ended.

- It seemed the Emperor's plans were to shelve his sons. Some that had more Administrative abilities (like Guilliman) or more technical skills (ie: Vulkan) probably would have been re-purposed or yes, allowed to rule their local systems. He apparently had apartments set aside under Terra for their retirement.

A more logical approach is that if the crusade had gone as planned, and most of his Primarchs survived, and most did not have a role he could think of post crusade, the simplest solution would be to set aside his greatest generals in the event that he needed them again (Ork Waagh, Necron Tombworld, Tyranid Invasion)
