It would be great if I could access the diff without having to loads the json string

I would like to be able to get the dict that is built up in the following function before it is serialized into json:
https://github.com/cloudtools/troposphere/blob/47cc47ae9f8fc9e933eb1d52df04efc0dc6d2c9b/troposphere/__init__.py#L451

As it stands, I just use json.loads on the to_json produced string to get the dict I am after.

Start in troposphere/__init__.py at the linked function around line 451, and inspect how the dictionary is built before it is serialized. Expose that dictionary so callers can access it without parsing the to_json string; done means the pre-serialization data is available through the library API.
