I apologize if this has been asked/answered before, I searched for a while and didn't come up with anything, but I wasn't really sure what to look for, so it may have been there.

Anyways, I'm using the map editor in Twilight.  I've made a custom map with a fixed starting location for each of the races, but there's a problem.  Earth doesn't look like Earth, Mars doesn't look like Mars, Jupiter doesn't...you get the idea.  Is there a way I can get the race-specific home system graphics on a custom map, while still keeping them in a fixed location, with altered stats?  IE, can I have Earth looking like Earth, but without the color & size of Sol changing, the number of asteroid fields changing, to their default values?  Can I have Mars looking like Mars, but still have it start as a "barren" world rather than a "habitable by all" world?  I saw that each race has an entry in the "CustomPlanets.xml" file, which seems to specify how each planet should look, but I wasn't sure how to transport that data into my map file.  I opened the .GC2Map saved file of my custom map and saw similiar looking syntax, but can't figure out how to put the CustomPlanets data into that file without making the game crash upon attempting to load the map.

Also, on an semi-unrelated note, is there a way around the 5 planets-to-a-star limit, or a way around the stars-must-be-7-tiles-away limit?  I'd like to get the entire solar system in there rather than just the most prominent planets, and I'd like to get Alpha Centauri a and Alpha Centauri b a little closer together.

Anyways, hopefully that isn't confusing anything.  Any help will be greatly appreciated.
