Is mod idea this Possible?

Is it possible to change the way skyrim's 3-4 stats regenerate ad drain from their respective pools?

 

For example, If I wanted to make magicka/stamina regenerate slower the more you used and drain fro health if you tried to cast/power attack at 0 of either(+having it stop at 10 HP or if you don't have enough health to cast/power attack so it would only kill you if you had Exactly enough health to cast/power attack)? In another way, is it possible for shout cool-down mechanics to be changed so that the script instead drains the cool-down "value" from stamina and gives shouts a 1/3/5 second cool-down to prevent derping the physics engine?

 

Or is this stuff hard-coded and unmodable?
