There is a total convertion mod that is supposed to add what you are looking for, but ive never tried it. I can provode a link to that if you like,
Edit: With the above mods. Ive tried them all together and they seem to work well.
You should download the leveled list tool that allows you to add all the lists from all the mods in one file. Its included in Puma's downloads. It will help avoid any errors or overwriting between mods. If you need that I can provide a seperate like as well.
