@Doitsu: The K5 version of the hack works very differently than on the K3 (it doesn't even ship with custom fonts), so you're free to cherry-pick exactly what you want to change, and it doesn't do anything by default, besides setting up the groundwork needed for the rest to function
.
It's still not terribly user-friendly, but way less clunky, more flexible, and completely controlled through KUAL, so no need to play with specific files, or rename stuff.
I'll just add a dedicated entry to the "Font Override" menu
.
