Using lots of thinking and tools like Pk3ds I was able to replaced Rada and her pokemon for Faba and his choice of pokemon. I also heard some suggestions on how to improve Faba pokemon and so far it's been wonderful. Here's a video showing Faba in action on multi battle. I have the romfs.bin available for those interested. You need hans to run it and I think it should work on others 3DS. Let me know if it doesn't work.
