its the hardiest thing in the world to do
Really now?
You'll have to make the mod yourself but that's easy to do. Copy the RaceLogos.tga file from your textures folder in the Rebellion install directory. Make yourself a new folder in your mod folder, make a folder called textures in that, and paste the file in the new textures folder.
Open the RaceLogos.tga file in an image editor. The player symbols are the ones in grey scale. Make your own symbol in grey scale that's about the same size and replace it over one of the existing symbols. There's also the smaller scaled icons at the bottom that are hard to see, and these are pure white.
Save it and enable your mod in game and you're new logo should replace the old one.
