I seem to recall many years ago that it was stated that there would be SKINS developed that would give one faction’s ships the look of another. Say for instance you have an algos, but you’re a Minmatar. That algos could have a SKIN that has a reddish brown Minmatar paint job and a Minmatar symbol instead of a Gallente Federation symbol. This way if you have a Caldari in FW who favors Gallente or Minmatar ships they wouldn’t have to fly around with the symbol of their enemy.
Now the concept I recall was even more in-depth. I believe it was a Gallente battlecruiser with not just a color palette swap, but actual Amarrian textures with the raised gold plating. I’m not even sure it was a SKIN. It may have been that the plan was to allow players to build these ships as such, essentially introducing multiple empire specific aesthetic base models for the same ship. It had to have been 7+ years ago at one of the fan events so my memory is a little rusty.
But I’m not calling for something that drastic (although that would be cool too). Just a simple change to the color palette and faction logo. Heck, even if the only difference was the faction logo that would be some progress. Or perhaps there could be a default option to swap the faction logos between the four empires.
