I have an Idea how about in victoria 3 or the next expansion pack they create the "settler" pop and you can recruit those settlers into military like units where once you recruit the settler you can move that settler to other provinces then settle them down increasing the provinces population by 3k per regiment of settler once the settler settles in a province that it was not recruit in the pops will have a high chance of changing professions so you don't have a bunch of settlers just staying settlers instead of farmers or factory workers post what you think below
