Honestly out of all the pirates the Corona Flamer is the only one who reads as particularly recruitable in the game as-is, mostly in that she actually seems to like you and form a rapport with you. And given she's also an insane pyromaniac, that speaks to about how recruitable the others feel without enough extra material that you'd essentially just be going 90% of the way to making a new character from scratch
That's a good point, I would be fine with being able to recruit the Corona Flamer in that regard. Though, can't the same be said with the Bored Jumpers and Rat Raiders? If your nice to the raiders you can become friends with them, they only fight you because so they don't get in trouble with their boss I think.
And with the Bored Jumpers, they care enough to meet with you during the pregnancy stage, as well as to give you their child if you have a kid with them. Additionally, when you visit the nursery on Tavros, you can send them a photo of their child and they will respond happily.
I mean I get the Cyberpunks because there isn't much in the way of interactions with them. However, with the interactions with the rat raiders and jumpers, couldn't there be the possibility of a recruitable member from these two factions?
