Race Fallout races - Super Mutants and Ghouls

[Trolls]

Having been playing Fallout 3 recently, I've been thinking about how to incorporate the setting's ideas into D&D, or even how to run Fallout game when the Amethyst book is released.
For Eberron, the conversions are easy. Super Mutants become magebred humans, with ghouls becoming Mourning victims.

So anyway, here are the stats I'm playing around with. Let me know what you think!
