Not entirely sure, not tested either, but I think what you want is 
something like 'doc python:test(hasattr(model.aq_inner, 'get_default'), 
model.get_default(), model)' so that if the model is a Folder or 
Publication the doc variable will refer to it's 'default document' and 
if it's a document the doc var will refer to itself. Note that of course 
you will have to check whether the doc is actually a document object 
afterwards (can be None if a Publication or Folder has no default 
document) and whether it has a published version (something like 
doc.get_viewable(), returns either the public version or None).
