Difficulty rebuilding an edited Pokemon Sun rom

[WildTorterra]

So, I'm trying to edit Pokemon Sun's ROM slightly to allow for other Pokemon to use another Pokemon's exclusive Z-Moves (i.e. Torterra using Pulverizing Pancake) to then use in Citra.

Here's all that I've done so far:
1) Using Godmode9, I dumped Pokemon Sun's rom as a .cia
2) I used Asia81's packhack (V9 specifically as V12 didn't work) to extract the CIA and get the files shown (I did not decompress the code.bin)



3) I compiled all the output files into their own folder, and then open said folder with PK3DS.
4) I made the changes that I wanted to make. I attempted to rebuild as a .3DS file within the program, but it wouldn't complete and gave me an error.
5) I moved the files back into the folder with Asia81's PackHack, then attempted to use that to rebuild everything into a .3DS file. While it did "complete", the output was a 0 KB .3DS file (which I'm assuming means it didn't work).
