Interesting story. It would take a truly extraordinary psyker to defeat a Lord of Change, and the Imperium does have a few of those. Well that sorcerour would have only one or two names. His birth name and the one after accepting Chaos, there could be multiple titles added to after that.

I suggest you do not try to think of a name from scratch and instead do what most authors do. Read about gods, myths, history and legends ,choose a name from there, change it a little, develop the story more then add the titles.

As for a name, heres a few:

Ahrimanus

Tubalcaiman

Alhendors

Alhambra

Meroton

Hope this gives you ideas.
