Actually your best bet would be Scarlett. She can still be found at most Family Dollar stores single carded for about $2. with a little paint she would be perfect. Ive thought about doing one myself, and youre pretty much doing what I was going to do. Id suggest B.A.T. arm from the joe line, Its actually more Human looking than the BD. If you dont know what that arm looks like check out the arms on my Bollux in the Droids custom challenge thread, those are B.A.T.arms.
