Cannot relocate stock planets

[A425]

I'm having some problems relocating stock planets for my WIP mod.

I replaced the sun with a placeholder, and I'm trying to make the stock planets orbit around another star called "The Sün"

First, I tried modifying the System.cfg file provided with Kopernicus but, though it worked, the KSC view broke and Kerbin dissappeared (Though when you launched a vessel, Kerbin was there and the map view worked properly).

My second approach was to create .cfg files for every planet, that made (Or at least were supposed to) the planets orbit around The Sün. There's no need to say that it didn't work, probably because the file is wrong.

So, I don't know which of those ways is the right one, or if it's anything I haven't even thought about.

Can anyone help me?

Here I have one of the cfg files:

 

@Kopernicus:FINAL:NEEDS[Kopernicus]
{
    @Body[Kerbin]
    {
        @Properties
        {
    %rotationPeriod = 21600
    @ScienceValues
            {
        flyingLowDataValue = 5
        flyingHighDataValue = 4.5            
        landedDataValue = 4
        inSpaceLowDataValue = 3
        inSpaceHighDataValue = 2.5
        recoveryValue = 3  
            }
        }
        @Orbit
        {
        %referenceBody = The Sun
        semiMajorAxis = 13599840256
        inclination = 0
        eccentricity = 0
        longitudeOfAscendingNode = 0
        }
    }
}

I managed to make the cfg files work and the KSC view kinda works (I mean, Kerbin is there) but now, the daylight cycle is as messed up as it can be  (There's no star, It's always nighttime)
