You're making simple things needlessly complicated.
Booklet version of KUAL works on Kindle Touch. And so should the jailbreak hotfix and MRPI.
The hotfix is what adds that ;log command into that JSON file.
I used kindlet (azw2) version of KUAL on my old PW1 then later replaced it with booklet version while my PW1 was on firmware 5.4.x.
