I have my Mac configured to require a password when it goes to sleep or when the screen saver comes on. When I wake it up I'm presented with a login box and the screen behind it is flat black. I would like to change or add a background to this unlock screen but I'm not sure if it's possible. I'm aware of how to customize the background of the OS X startup login screen.

There is no resource in /System/Library/Frameworks/ScreenSaver.frameworkto change.
There is no mention of a wallpaper path in /Library/Preferences/com.apple.screensaver.plist, ~/Library/Preferences/com.apple.screensaver.plist or ~/Library/Preferences/ByHost/com.apple.screensaver.MachineID.plist.
Secrets.prefpane doesn't have a setting.
Using fs_usage to see all disk paths accessed during locking and unlocking the machine via Ctrl-Shift-Eject yielded no unexpected disk accesses: No default wallpaper path, and all accessed plist preferences files (predominantly all variants of .GlobalPreferences, and surprisingly com.apple.loginwindow) mention any file path.
I conclude: It's very likely impossible.
