A Short Victorious WWI, either by the Entente or the Central Powers, would see AH survive, albiet with some sizeable chunks sawn off in the first place, and in a German stranglehold in the second. I'd go with the Entente victory myself (US gets involved 1915? Ottomans on the Entente side?), if only because if Germany wins big, they are likely to suffer from "victory disease" and drag AH into yet another war somewhere down the line.
