Sure.

Spoiler:

{
  "Options": {
    "sizes": [
      {
        "default": false, 
        "height": 680, 
        "ratio": false, 
        "width": 450
      }, 
      {
        "default": true, 
        "height": 300, 
        "ratio": false, 
        "width": 300
      }, 
      {
        "default": false, 
        "height": 1000, 
        "ratio": true, 
        "width": 1000
      }, 
      {
        "default": false, 
        "height": 450, 
        "ratio": true, 
        "width": 400
      }
    ]
  }
}

I also noticed after running calibre-debug -g

Spoiler:

Traceback (most recent call last):
File "site-packages\calibre\gui2\ui.py", line 236, in initialize
File "site-packages\calibre\gui2\actions\__init__.py", line 147, in do_genesis

AttributeError: 'unicode' object has no attribute 'get'

EDIT1: The latter error occurs if you delete the .json file completely.

EDIT2: Additional information: Even if the plug-in starts, creating a new item menu always creates a "Default" item.
