Dawson or Zoe Saldana would be ideal to play Nick Fury's (much younger) girlfriend, Valentina Allegra de la Fontaine. Val doesn't sing but she does kick ass.
Oh wow, either women would be great (Zoe more, because we know how athletic she really is) or perhaps Paula Patton, who also showed some brawn in Mission Impossible 4. But I don't know if she sings or not.
