Exactly what it says on the tin...
Have the Kingdoms of Belgium and the Netherlands along with the Grand Duchy of Luxembourg join the German Empire on its formation in 1871. There must be a minimum number of changes before then and preferably the PODs must be no earlier than 1815.
I'm guessing that:
My suggestion is that the Kingdom of the United Netherlands does not break up in 1831, becomes very pro-German, joins the Zollverein, is an ally of Prussia in the Franco-Prussian war and joins the German Empire on its formation.

I'm guessing that:
- It would be relatively easy to integrate Luxembourg as it was in the Zollverein at the time;
- It would be difficult to get The Netherlands to join, but not ASB;
- It would be very difficult to get Belgium to join, because even if the Belgians wanted to join the other great powers want to maintain Belgium as an independent and neutral nation.
