Sounds like there was a lot of drama that I missed. I guess the communist-esque mod I noticed earlier was purged as well? Regardless, though I saw no "Nazi" like symbolism in a roundish black/white/red colours-theme, one has to wonder...
While building a full faction mod is a lot of work, if all you want is to play with those ships, it should be relatively straightforward to build a mod that just adds a few specific player-only hulls to the game.
How would anyone go about doing this, if we don't have the base files for the ship-sets? You are right making a ship-set swap or cloning from an already existing set might be straight-forward, (Though I have personally never made a mod, surely not for this game) but without the original files we got nothing.
Thanks for answering the question though, just my luck the one ship-set I liked got purged.
