Possible to mod a race to be immune to suffocation?

[Lemony Lime]

How might I go about making it so Engis don't need to breathe? I want to do a playthrough with a custom ship, that relies entirely on drones, and starts you off with a single engi, in a much smaller than normal ship, without any O2 system at all.

Special features of races are hardcoded and can't be altered.

Maybe edit the blueprint for the "Engi Med-bot Dispersal" augment to make it stackable, and give yourself three?
I'm not familiar with the heal rate it provides or whether 3 would overcome suffocation.

Or you can use the ghost race, which doesn't require oxygen.

Ghost race are immune to suffocation and unless you've already added a new race inplace of them then just change race X to the ghost race.

Or you could edit the rate at which it heals your crew so that one is sufficient.
By default it starts at 0.25, and I belive you need it around 1 to counter asphyx damage.
