In what universe ? Alsace-Lorraine wasn't even discussed at Versailles as it should have been.
Germany was lucky to be in one piece after WWI, so no, they aren't going to get Austria.
I wouldn't say that much. Forcing a dissolution of Germany is one of the things which would likely have caused Germany to fight on, and while the Allies had by far the upper hand, an invasion of Germany proper would have been extremely difficult, even after the armistice.
