I found on Thoughthammer a pre order for a bag of plastic Cthulhu figures. It lists 6 large (I figure these are the ones from the CoC card game) and 24 small figures for $11.21.
It lists possible uses as replacement Doom tokens or as sucess tokens for the card game.
I'll buy them for the game, but even if I didn't like the game, I would buy them anyway.

I also posted the info on the Arkham Horror board.
