I personally want a faction similar like HMI in concept, but more offensive, using a jury-rigged ship that produces the highest damage output of their class with a built-in weapon with one big downside, their ship cannot be recovered no matter what, their ship is not built to last, their purpose is just to hit hard and hit fast.
And maybe throw campaign mechanic as well like need a lot of crew, can't stand hyperspace storm and corona, but cheap and really fast to repair plus recovering CR, encouraging players to keep going from combat to combat.
They can be high tech, midline, low tech or even better, an amalgamation of the three to produce the highest damage possible. Will this faction make sense? Maybe not, they probably tear apart the lore and annoying to deal with if you got the short end of the stick, heh.
But they probably fun to play with Iron Mode.
