AFAIK, since PI structures will be the common fighting point in Dust 514, the actual issue doesn't appear to be that bad.
Planets with pre-existing cities and the such will be the biggest hurdle, but PI combat sites are literally copy+paste. PI structures having a valid, reusable schematic to turn sections of the world into arenas isn't a stretch. At the very least, you have thousands of randomly generated terrain with printed out combat sites.
