The Separatists were indeed inspired directly from Engi B, though their cruiser has a completely different sprite.
The MV Bosses were added with the intention of spiking difficulty, and depending on the challenge level you select they get harder or easier. If you select casual, they just won't spawn at all (with no penalty to score either.) So far I havent really heard any complaints about their difficulty other than when people trigger a somewhat troublesome bug from reading the Atlas's in-game "wiki" pages, which increases the internal sector count trigger and can cause MV bosses to spawn much earlier than intended. There's unfortunately no proper fix for this at the moment.
Near the end of my run I went down the new tree lizard questline and ended up with some boarders of that species but they must be bugged - they would be practically invincible as their healing was so high until they switch form and are killable for maybe 10 seconds. It was a huge effort involving detonating my Zoltans in the room as soon as their form switched to actually have enough DPS to kill them. I would advise people to avoid this questline until its fixed as in most situations it would be a game over.
Yeah, this was a funny bug, though also a fairly annoying one. The easiest solution, obviously, is to just not pick the option that makes them board you, since there's one option that's always correct and one option that's always incorrect. If you do pick the wrong one, you can use the KILL command on the console to get rid of them.
