Here is the biq that you wished. As you could imagine with the leaderhead posted above, the next civ are the USA. As you wished, all civs but the USA can build settlers normally additionally to their autoproduced clans/settlers and each normally built settler costs one population point (so here the settings don´t get too much out of balance). There was no playtesting with that biq and therefore I have no idea what awaits us here. This is a big experiment, but - the whole life is a complete risk and it always ends deadly.
