From a quick read of the docs, it looks like you should set the unpickler's find_global attribute to a function you define. This function can first attempt to load the desired class (see pickle.find_class() for an example). If the load fails, then return a placeholder class that you define.
This won't give exactly the result you ask for, instead of None in the dictionary you will have instances of the placeholder. You could then post-process the dict to change the placeholder instances to None if you like.
