How to replace one character with another

[DocStrange]

I saw on ESH that it's possible to replace Olimar with Shadow and I was wondering if the same would be possible for Jigglypuff. I messed around a little, but Jiggs has fewer (I believe) model data files than Shadow. Should I just add the rest of the data in?

go to texture data click export

Do the same thing with the ef_name in the fitname.pac.

For animations do the same with fitnameetc and fitnamemotion in the fitnamemotionetc.pac

File size limits apply. And if it works the specials won't. Ike over Marth works. Specials don't though.
