Finally tried Lost Cities!
Ymmv, I think it only works as the ONLY structure generating mod in the world. Otherwise not only does it collide with everything, it also clashes drastically in the sense of style.
The collide with everything part is the worst though. Villages, pillagers' outposts, and other structures were completely ruined.
It is also pretty darn empty, kind of what I thought looking at the images on the mod page. Which strikes me as odd somehow. If they are so empty, they should be a lot more destroyed. Most buildings are intact somehow.
Still, as the only structure generating mod it would be neat. Especially if you are more interested in destructing intact modern looking structures or want a shell for a modern "village".
