If this helps, here's a Successor's variant:

If the faction controlling Perdiccas loses Alexander's body, or buries 
it outside Pella, remove Perdiccas and replace him with Seleucus.

This gets Seleucus, historically one of the more important leaders, 
into the game more often, with an appropriate regional pattern of 
support.  In the real contest Seleucus was Perdiccas' deputy, but 
assassinated him soon after Ptolemy stole Alexander's body.
