I was thinking of a mod where the belgian war for independence failed! (Basically make a strong Netherlands ruling the Benelux with possibilities to expand to the Ost Rhineland and Ost Friesland in Germany and for Nord Pas de Calais, Picardy and if possible add something like Northern Champagne to smooth the borders).

Undig the American dug Panama Canal since Britain already has the Suez Canal to link to their trading partners in Asia and the south pacific.
