I've just started the game but you probably would not want me to translate as my JP->EN is very poor. I can however offer my assistance in editing the script in terms of context and flow.
If anything is to be done, I think someone needs to figure out how to extract the script first. As far as I know, it is a heck of a lot different than what I'm used to.
Probably head over to the VisualNews Gemot (google it) and announce your intentions over there. They are well experienced in the art of fan localisations over there.
