I think it would demand AH to behave very in manner which we would categorise as borderline insane. A thing most people tend to think when we talk about AH being partitioned are that Germany and Russia leave a strong Hungary. I think that's unlikely. A strong Hungary was a benefit for Austria, but neither germany nor Russia would have any interest in it. So I think Germany will push the Romanian border to Tisza (except for Banat), create some kind of South Slavic state, give Italy Triest and Dalmatia (but keep Fiume to themselves), setting up Backa-Banat as some kind of Balkan Switzerland, include a greater Burgenland in Germany (likely includes Bradislava/Pressburg), give Slovakia independence (likely include Carpathian Ruthenia) and leave a small weak Hungary as a buffer state.
