I understand that the names on the map are names in English, but still...
The language in areas ceded to the Netherlands and Belgium is Germanic, and IMO the new names should be in Dutch.
Aix-laChapelle -> Acken
Cologne -> Keulen
Cleves -> Kleef
Coblence -> Koblenz
Also, I don't think
that Wallonia would be expanded to Plattdütsch and Franconian (both Ripuarian and Moselle) speaking areas, east of present Wallonian border.
IMO, Germanic speaking areas ceded from Germany to Belgium should be incorporated in Flemish
part of Belgium or maybe even make a third, Frankish
part (Eupen, Malmedy, and Sankt Vith included)
