Ran this yesterday and it was a ton of fun, great job!
Took us about 3 hours, and the ship exploded at the very last roll, but the players all had a blast both figuratively and literally.
I had 4 players so I replaced Charred Patch with the fourth PC's mirror, but I think if I did it again and (again) had a scientist PC I might replace Charred Haste with them instead.
It makes the timeline a bit easier to think about, and gives that Charred PC more visibility.
All in all though, very easy to run and a lot of fun.
My one ask would be a player-facing map - could literally be the (excellent) GM map with just the text and vents removed, but it would have been nice to be able to show them a proper one rather than my quick paint mockup.
