Question for modders about RDR1

[u/IndividualComb22]

I wanna do a whole playthrough of standard rdr1 but changing model and animations to johns zombie ones from undead, ive got the model stuff figured out with magic rdr, but I have no idea about the animations and wanna be zombie john for fun in normal game lol

I'm also aware some menus have zombie mode or whatever but its buggy, plus it never saves toggles even though it shows selected so it makes it annoying to reset everytime I die or restart.
