I am wondering how to make weapons usable on classes that can't equip these weapons. (EX. Sniper able to use axes) Can I use FEFEditor to make this possible?

I've been digging through GBATemp and Serenes for awhile trying to get answers, I can't seem to find any. I am using FEFEditor and its built in FEFNightmare4, following the tutorial on editing character AIDS. I've been attempting to open ROM3.lz, only to have it open to nothing. Options in the file show that the file is open, but nothing shows up. I am running Java 8 Update 201 and running roms on Citra. Any Advice is welcome. EDIT: I'm able to open modules with the program, but I am still not able to open ROM3.lz.
