Well, the "new" primarchs would go charging in a spiral assault in two groups (5n5) One of the forces would land up getting close to the Eye of Terror and save Creed and his dudes on Cadia. Russ could re group with the 13th and find Corax.

Now, a truning point after Abaddon`s demise, Lorgar awakes and, being the first heretic and arch-curruptor, takes on the lead. He could currupt one of his younger brohters (who maybe is a psyker) and give him the same plan he used to currupt Horus to do so on the brother who leads these 5 primarch. So, those 5 would fall to chaos, but neither their re-found brothers, Corax, Russ and the revived Lion would notice it (yes, they would join forces in this case to take command in the IoM). The new 5 heretic primarchs would set siege to the Eye of Terror (all being a well orchestrated play of Lorgar and the gods). The undisovered heretics would join Russ, Lion and Corax to Terra, breaking the slaves of the High Lords and the Inquistion on the way (while secretly currupting the population). They reach Terra....

On the other side, the other 5 lead by another primarch fight the resurected Guilliman, who has always been a cunt..... and the Ultrasmurfs..... They win and on the way destory the hive fleet in Ultramar. They too reach Terra

Also, the new heretics could have finnaly Khornated the Blood Angels and their successors on Baal.

Now, the new primarch and the old returned ones (including Vulkan who joined the forces comming from the east and north) set up shop on Terra.... But now the legions stationed around the EoT do what they were meant to: Join the, once again, united Lorgar, Magnus, Perturabo, Fulgrim, Angron and Mortarion. So they wage massive slaguhter and spread pain and plague till they reach Terra.... blah, blah, chaos wins, end of the story :P
