Well, if it is to any comfort, we do have options as far as nations that far east go. Tocharian may not be it, and the Khotanese Saka may at best be sparse, however we do have some very powerful resources for Sanskrit which will be of tremendous use. We can not rule out the future prospects for Aramaic or Syriac-related languages in order to add flavour to the Near East. This is merely a showcase on what kind of options we truly have at our disposal. We don't just stop once these projects are done.
