OK, here's a dotmap that I think could work for either a cultural win or a continental invasion win.
City A needs 3 border pops to even attempt an early invasion, so I would make that my first build and also one of my culture cities. City B would make a superb GP city but I think it's worth making a hybrid GA/culture city.
Cities C, D & E overlap with our culture cities so as to work their towns early on. C woud be a miltary production centre & D would be able to help with the occasional GA later on (it can be irrigated from the south for a decent food suplus.
The rest of the cities fill out the land mass and pick up the major resources.
I think I'd probably aim for a MC slingshot to get confucionism in city A. I would then bee-line metal casting to get the Colossus there also (4 commerce per coastal square will make those coastal cities pay for themselves pretty quickly). Shrine + Colossus will also add 10 culture to get that border out asap.
