As I feared, this can be indeed installed to sysnand with rxTools and FBI, but it won't boot unless sig checks are disabled. I should've figured this, it's pretty obvious in hindsight.
I was hoping for a quick method to boot CFW, but I guess it just can't be done with the currently available tools.
