Have you tried a conditional/try-catch block in your __init__? Something like 

    class MyDBConn(object):
        def __init__(self, **db_kwargs):
            try:
                db = some_db.connect(**db_kwargs)
            except some_db.ConnectionError:
                db = my_fake_db() 
            finally:
                self.db = db 

You might have to write an adapter to make sure you can treat the fake db and real db the same way, but that shouldn't be too hard.
