As much as it's a nice idea, this is the wrong place to be suggesting it, as NISA only localised it, they didn't develop it, and thus have no control over what DLC is released for it.
I also probably wouldn't hold out an awful lot of hope for the idea anyway, considering how the game seems to be designed.
