Since you kindly produced the picture I meant to make and never did, I decided to see about laying out cities...

The eastern half of our land, which is looking more islandlike all the time, seems pretty straightforward, actually. A few of these could be shifted around, but not by much due to city spacing rules. That, of course, leaves the hard work for us in trying to figure out what to do with the western half. Also of note is that
every single one of these cities are coastal. The Great Lighthouse would give us +2 trade routes in every one of those, which is going to be at least +2 (initially, with internal routes) and later +6 or more commerce per city. Of course, the Colossus would also get us a lot of commerce, eventually, because of the large number of water tiles, but... this wouldn't even require citizens.
Green Dot (shares cow) is probably our best bet for getting it built, if we go that route, since it shares the cows, has a second food source in the pigs, and has several minable plains hills. (Also, it's another "plant on a desert to make use of a useless tile" city.)
Red Dot is the ridiculous food city we've been discussing. If we want to whip out the lighthouse, instead of building it some other way, I suppose that's the place to do it. Do either of you know how to find the minimum population after a whip? (I think it may be "no more than half may be whipped away at a time"...) I'm unconvinced it has the production to build things in a timely manner, though. (hmm... actually... a mine on the hill, and cut down the other forest... or maybe keep it until almost the end, actually... and deforest purple dot's land... that could be worth trying.)
In the North, there's Yellow Dot, which hits a ton of food resources. My money's on this being our GPP pump. I'm not sure what to say about it further, beyond that I wish the corn were somewhere easier to share.
Orange Dot is there to share the fish and get the stone and whale. I'm not sure it shouldn't be moved 1N. That would lose it the chance to use the fish, but... that seems like an excellent place to put the Moai Statues, which would make more water tiles not terrible, as well as reducing overlap and getting us off a peak. Yeah, I know I drew it there, but I'm really thinking it ought to be one north of that. It won't be able to share food resources to grow, but it makes better use of the land, and, if we have good worker support by then, it might not matter anyway.
Finally, there's Purple Dot, an otherwise worthless site, could be used in a mass deforestation ploy, at some point, but you only get that once, and it'd then proceed to suck until optics, at which point it'd only suck a little less. I haven't done the math, but I don't think that chopping down that many forests would actually get us there. That city is only there because there was space to fill, and that's basically the only legal place to plant it. It'd give us more trade routes, though.
West of those cities is harder, unfortunately. I think you're right that we can cram one in on the coast W of Timbuktu and probably sharing the wheat. That desert (again) hill looks nice, but I'm inclined to wait for borders to pop another layer before nailing anything down, I think. 1N on the plains forest could also be good, since it gets at the incense, but I kind of want to put a city near the FP grabbing horses and luxury goods. It'll suck to feed, unfortunately. Maybe share the sugar, and figure something else out for the incense.
