Did you try using a brawl mod with bone edits?
...
Both him and I are PSA modders. We should know.
Bone edits are either adding bones, renaming bones, scaling bones, moving bone placements, or moving bone IDs. All of which aren't generally compatible (and sometimes glitchy) with the respective characters without editing the character's animations and/or PSA. You either have to make your character's bones match the character you're making it over, or just make a PSA and fix the bone edits. There will never be a middle ground, no matter how hard you try.
Now stop dragging Off Topic. This thread gets enough of it as is.
