Yes, that is possible.  You might rather call the appropriate
workflow methods, however, as setting the attribute directly
breaks encapsulation;  for a one-time hack, it won't be too awful.

If I understood your original question, you have created a new

type object, "Card", based against the CMFDefault.Document Python
class.  In this case, the 'meta_type' of the instances will still
be 'Document', but the 'portal_type' (the ID of the type objects)
will be 'Card'.  I can't think of any time when I would want to
set the 'meta_type' on an instance to be different from its class.
