As the title says this is a pack of the seven chinese random map scripts already included in the extended edition (the ones you see in your map menu but can't select because they're locked if you don't have the expansion). Since the assets and models needed are already included in the game there will be no problem loading the presets once you added them to the game.
I don't know if a pack like this already exists, I just wanted to put it out there since I think the maps are quite nice.
If you wonder if unlocking the maps like that is allowed - let me just say that I treat xml and xs files as open source and it only took a few minutes to figure out how to do it :P
