That's never going to happen, due to the ruling in C:CSM, bottom of page 91, that says any character from those pages (90/91) may only be taken once. So by trying to take 2 Abaddons/Typhuses (Typhii?)/Arhimans, etc, would be a direct breaking of a rule laid down in the Codex
My points was that in C:SM, multiple typos existed concerning where a certain Codex rule should be enforced. Though as JWolf pointed out, the main rulebook provides a coverall ruling on uniqueness. (Thanks for pointing that one out )
