[Mod Request] Running. Stamina, Muscle, Fat.

[Planetfall]

Hello,
I had this idea bouncing in my head for a while and I'm wondering if it's at all feasible.
The concept is to give three new stats to all humanlikes. Muscle Stamina and Fat. And a system for different movement speeds (running sprinting etc.) I don't know what the best way to go about this would be as I'm not a modder. I have made a very rough plan for using the Needs system (attachment below) but I've been running into issues as I don't know the limits of what the Needs system can or can't do. The stats aren't finished and are probably way off balance (for example I'm pretty sure fat accelerates muscles gain atm which just makes no sense) but I don't think I have the ability to balance it myself. Also the stat sheet only covers the core systems. I would also love to also add new Drugs and food to better manage fat and muscle levels like vitamins, steroids, and weight loss pills. And traits that personalize the mood buffs and debuffs associated with each new stat. Say new traits that modify how pawns think about stamina/muscles; Bodybuilder (mood boost at low stamina slight mood debuff at full stamina as he/she always wants to be exercising) an Lazybones (more extreme version of the normal stamina mood modifiers so these pawns hate strenuous activity) and then traits modifying mood related to fat; Anemic (only happy when fat bar is low/empty perhaps a custom mental break to make them vomit if fat gets higher than they like) or a trait for someone who doesn't care at all about his or her self-image/heath. But I think it would be best of me to seek outside opinion before I go much further.
