Asajj Ventress has her own animations (and .combo has been tweaked to make it more like the X-Box version)
Ventress was given Starblades (similar to X-Box, cannot be sure since I don't have the game for the system)
Kit Fisto has a new lightsaber model
Force Bubble attack's effect tweaked (particle effects added to bubble to look more "realistic")
Kit Fisto's .combo "fixed" - there was a hidden melee combo included but it was previously inaccessible
Shadow issues with Kit's head resolved

Readme:
Load kit.lvl or asj.lvl as a custom side, and call for the correct hero name. Be aware that when using these heroes, they take up more animation/combo memory than the stock heroes, and as such you can't load a whole lot of stock heroes along with them (and you can't load both Kit and Asajj in the same level). This is why, for example, Kit only shows up on Alderaan in the Conversion Pack.
