Sweden has no interest in Northern Germany whatsoever. Neither do the Dutch.
Both also wisely refused to be dragged into any expensive adventures throughout the 19th, and had it gone as they wished, 20th century.
Denmark could be a possibility, but I am afraid a few Prussian regiments would at that point be sufficient to hold them off.
