Fair enough.
Hmmm... How to do it...
How about generating all of the planets, doing a spiral search to locate places of interest on each one, copying a blob--made of circles of random size and position?--around that POI, then pasting it on top of a similar POI--thereby replacing it--on Nauvis? The spiral search would naturally contain smaller POIs at the top and larger ones at the bottom, so a similar spiral search on Nauvis would give you a list of POIs to replace. (I would set the resource frequency to at least 600% to be sure that Nauvis has enough POIs.)
Does that sound reasonable and doable?
