One warning about using captured workers or rush built settlers.
I kept two enemy cities as a late game base so that I could attack and raze their bigger cities. I rush built settlers after the war ended so that I could get rid of the cities rather than see them culturally flip. I then transported the settlers to my home cities and used them to join one or two of my cities. The enemy had already used the draft and maybe pop rushing so both of these settlers carried a huge amount of unhapiness with them when they joined my cities.
Due to the poor 'cities in revolt' information in the game, it took me a while to find that my own city which was only about 10 hexes from a Forbidden Palace was so unhappy. Then it took me forever to get that city back in reasonable shape due to the carryover unhappiness from adding one or two very unhappy settlers. While every other city had a row of happy citizens, this "joined city" had a row of contented citizens with a few unhappy citizens setting up a revolt (despite having marketplace, temple, cathedral, and maybe a colliseum, with Bach & Cure wonders). So while captured workers or "rush abandon city" settlers can be added to a city, they might also add a lot of unhappiness to a city.
