What i'm thinking about (not sure how it would be implemented or if even possible without major framework change) is somethinkg like the below

{
        "_id":"flash_componentID",
        "_parentId":"parentID",
        "_type":"component",
        "_component":"flash",
        "_fallback":true,
        "_layout":"full",
        "title":"",
        "swf": "some.swf",
        "fallback":[
                "_id":"fallback_componentID",
                "_parentId":inherit,
                "_type":"component",
               "_component":"accordian",
               "_layout":"full",
               "title":"",
              "items": [........]
             ]
    },
