@ManuBBXX Like omega res stated, this thread is dealing SPECIFICALLY with the char.LGP file, and thus has ZERO affect on what sword models show up in Battle. A better place to pose your question is in the APZ re-release thread itself, if it is still open. Here was one method discussed in that thread to have APZs buster sword model and tex appear for every one of Cloud's swords. Beyond this, please search for the relevant modding instructions on how to edit this on your own:
"To use the apz buster sword for all models there are 2 methods. The buster sword is rtck. Copy and paste it so u have 16 total. Rename them from rtck to rtcz.. Dump ur battle lgp, add them,then encode the lgp. The model decides the texture and because they would all b the same model they pull their texture from the same place. method 2 is with wall market. Load ur kernel. Go to the weapons tab. Tell all the weapons to use the first model."
