There is a balanced systems mod out there, by Geoschmo, that makes the systems have balanced numbers of planet types and atmospheres. A version of it is including in FQM, but I don't recall if I ever updated it to the latest. Mods can't do anything to help with "5-sided maps" in SE4, however. For that part, you would have to edit the map in the map editor (It is generally better to generate a map in-game, save it, and load it in the editor, than to generate it directly in the editor.
