A mod that increases the life of just named characters such as generals, notables, companions, and the player?

[Rivus]

How hard would it be to design a mod that raised how much life named characters have?

I would like to see enemy generals to have more life than your average troop, maybe twice or three times more than your average troop. I like the idea that named characters can become semi-damage sponges and maybe become more of a threat on the battlefield than your average soldier. This would be true of the player and maybe his companions as well, think like how in Dynasty Warriors where you might encounter a general who is much stronger than the average peon.
