The main problem I have with using Wiiscrubber or any method that involves modifying the original ISO is that I have to repack it every time and make a new copy whenever I want make any modification, or just test anything. It's not really an efficient setup for quickly testing mods.
On an unrelated note, I would like to know how you shortened the length of the sword. Was it via one-slot resize? And if it was with that, which axis did you use, and was there an additional thing to it or just the basic thing of renaming/reparenting the EyeYellowM bone and/or renaming the YRotN bone?
In regards to the sword's size, the sword model's just kinda shorter than the original, I didn't modify any of the bones ¯\_(ツ)_/¯
