riurik, I just laving his lack of a face as an Avatar feel free to play him. I would just play any key characters not already reserved. 

Yog, The problem with the Phantom Stranger is that he is much, much too powerful a Character to play. Game balance basically goes out the window, falls 100 stories down, hits a pile of bricks, gets trampled by a bull, blown up by dynamite, set on fire, and hit with a fire hose :P 

Andrew Bennett should be fine, though I presume this would be the heroic version :P 

I've never heard of Scratch until now (seems like a more obscure Tasmanian Devil) but he should be fine too.
