I always wanted a better death-handling system, but you just can't mod something that will be reliable in this respect. I finally came up with something that I didn't even need to mod. Whenever my PC dies and I have to load the last save, I use the console to showbirthsignmenu and I randomly pick a new new birthsign. Note you can do this without having to worry about your skill levels being set. Then, depending on what birthsign comes up, I play according to that sign. So, if it a warrior, she acts like a warrior, or a mage, she acts like a mage. This makes playing very refreshing with just one PC. Once, my latest female PC got the Lady birthsign so I roleplayed her as more of a noble person who didn't wander into dungeons, but she died when curiousity got the better of her while taking a little walk with her ladies-in-waiting.
It would be better if you could change classes with the console but that resets your skills, even with the special method of making a new save without closing the console and pressing Done. To get around this, I made some extra birthsigns that I could substitute for classes, and these also give her some varied abilities.
I also make a penalty for dying. Each death takes off 5 skill points and one attribute point, randomly picked. I use the console player.setav command for this. This makes you be VERY careful about what you make your character do, especially at higher difficulties.
So, try it out. It takes a littel work after every death, but so the more reason to avoid getting your character in too dangerous of places.
