Khameleon only wanted revenge on Shao Kahn for the near extinction of her Saurian/Raptor race and enslaving her homerealm, and with him gone/being punished by the Elder Gods now, she wouldn't have much reason to be in MK10, story-wise. If they wanted to use her, they should've done so in MK9. Maybe a Wii U version of MK9 will do that (since Khameleon was exclusive on the N64 version of MK Trilogy and the Wii version of Armageddon).
