So I came back at it again. With the release of Ultra sun and moon I had to have both of these characters as companions for the game. I used the game ultra sun to do the changes but I think these changes should work on Ultra moon too (I haven't tried but wouldn't mind to have someone to help me with that).
Instead of going to the files and replacing models on the garc files like I did in sun and moon, thanks to pk3ds things have become much easier. All I needed for this was pk3ds and the luma patch. I will make these available to download after I fixed some stuff but they're almost workable. Instead of replacing Rada because that came with problems last time (if you advance on the super multi battle you would notice faba instead of female breeders) I replaced Lillie this time and so far I found zero problems since I think she can't be your rival on the battle tree. All that's left like I said is to change her lines to better fit the villains.
If anyone is interested in the process I can explain it so feel free to ask but for now I will leave you with a video of the hack.
