Yes, this could be added to Emacs, and IMO would be a useful feature.

Suggested implementation:

  . import the Unihan_Readings.txt file into Emacs
  . add Makefile rules to produce a uni-unihan-readings.el file from
    Unihan_Readings.txt, which defines a char-table where each
    character has its kDefinition property value
  . code a minor mode which will show in the echo area the value of
    the kDefinition property, if any, of the character at point

Patches welcome.
