I think in MK6 it should be difficult to access secret characters. Like Jade, Smoke, Noob Saibot in MKII, Reptile in MKI. But I think they should have their own moves and the difficulty level should be 'upped' on them when you fight them, they need fatalities and maybe their own NEW stage, classic as well as new characters would be cool, and make if you beat the character you get to control the character. These characters should have endings, and bios as well... some REAL ORiginal secret and hidden characters would be nice... oh yeah if they have their own stages, let them be fatality stages and once you unlock the character, beat the game with them or something else to unlock their fatality stage... shoud good?
