The addon is for DarkRP. Since starwarsrp derives on DarkRP, then yes, it will work for starwars rp as long as you can still configure jobs that can do the missions like DarkRP does it (see the video). I don't guarantee anything though.
Soldat-hevy Yeah. You can change the models for the NPCs and you can change the models for the smuggle missions. You can also create as many missions you want with your own models and objectives.
