Well, the title pretty much says it all. We all know how Germany dominated by Prussian militarism turned out and brought us such wonderful stereotypes such as heel-klicking and giant mustaches. How would a Germany united and dominated by Austria (possibly with the inclusion of B-M and Hungary, though not necessarily) turn out?
The closest thing to such a timeline I can think of is Jimbrock's "Zwei Adler, Ein Kaiser", where Prussia and A-H are brought together in a political marriage, and might end up with the rest of the German lands.
