I've pushed today some feature which I originally developed for the nextgen terrain shader - the idea is to treat urban textures as an overlay to the normal scenery - some simple example here:
(you can see the original landclass showing between the houses and roads).
We can now do the same thing for the current scenery - so ideally cities no longer look like they replace the landclass, they look like they're built on top of the surrounding landclass (the currently best working example is Cape Town (FACT for the closest airport).
So what I would need is someone who can do a better job with city and town textures, cutting suitable holes into them. Basically we want to retain roads and houses (and some gardens) and otherwise open up such that we see the terrain underneath shining through. This requires some experimenting and tweaking to get right - for instance for parks etc. it may be best to just use 50% transparency such that they just acquire the right hue.
Anyway, the quality my graphics software skills can reach with this is limited, so to get better I need someone who is actually good at this.
