Another possibility shown here. Greece is not updated for this TL.
This map portrays MAXIMUM REPUBLICANISM and is not reflective of what I think will actually happen in this TL.
The areas with slashes through them are uncertain areas. I believe that even with successful Hungarian and German revolutions, that Prussia and Austria could survive. Croatia is an area likely to be occupied by the Hungarians, but I don't know enough about the area in the period to know what would happen. Poland is shown with Galicia, as I think it would be acquired by either Russia or Poland in the event of a successful Hungarian revolt.
Of course, Russia could intervene on the side of both Prussia and Austria against the Revolutionaries and it would result in a German border much like the previous map I posted.
