I will say for one thing that it strikes me as a little strange that the Von Carstein's would willingly support Nagash, seeing as how he would just dominate them. They've always seemed fairly independent-minded, along the same vein (pun intended) as Neferata; ie. seek to build and rule their own Undead Empire -- like Vlad always wanted.
