Perks for survival mode

[pra]

Are there any mods which add/change perks specifically for the survival mode? Lead belly kinda goes into that direction already, but more could be done.

 

I was thinking about things like:

- Strong immune system: at first decreases the probability of getting sick, later allows you to sleep off diseases

- Heavy sleeper: first level allows you to sleep for any duration even in a sleeping bag. Second level allows you to sleep while sitting. Third level allows you to sleep anywhere, like in Morrowind.

- Raw eater: raw food satiates better, processed food satiates worse. At the second level you can no longer eat processed food, but raw food satiates even better.

Mutually exclusive with

- Gourmet: Processed food satiates even more, but you can no longer eat raw food. At the second level, the satiation doesn't change, but you get the food's effects even if you eat while hungry
