Extracting texts from a PS4 pkg and inject em in its PS3 version?

Hi guys,

So I only have a PS3, but I really wanted to play a game that was localized in the west only for the PS4, but is only available in JPN for its PS3 version. Do you think there's a way I could extract the texts and menus from the PS4 version and somehow inject them in the PS3 files? I assume there's a lot of reasons this is actually impossible but I'd blame myself for not even trying...
