Get the English to call the Germans Dutch instead would help. 'German' is a slightly romantic way of referring to the Deutsche that only entered the English language in the late 14th century (from 1st century BC Latin), and it was used side-by-side with Dutch and Anglo-Norman 'Almain' until the 16th century. With German used for the folks living in Germany, 'Dutch' was open to be used in reference to the Netherlanders who had received political independence (along with a close relationship with England at the same time).
If the Germans would've kept being referred to as 'Dutch' (and 'German' means 'Germanic' like it does in most language), there's a lot of room for 'Netherlanders'. Unless, of course, someone didn't get the memo about not using 1st century Latin and starts calling them 'Belgians' instead.
