@atango: Would you like to make a try? I'm curious about this possibility.
Here attached there are two files for english language, en.txt for the menu and EN.kbd for the keyboard.

you can rename it kr.txt and translate the menu in Korean, and change the keyboard as well.
then place the menu file in:
/system/language
and the keyboard file in:
/system/language/keyboard

that should add Korean language to your choices, and maybe keyboard.
