When I chatted to TOS/TMP makeup man Fred Phillips in 1983, he mentioned that the expensive alien ambassadorial costumes were ordered up because there was a plan to have Nogura addressing a "Journey to Babel"-type banquet in which they are told of the gigantic cloud heading for Earth. That idea didn't progress because Robert Wise found most of the masks wanting, and relegated most to background scenes, where little detail would be evident.
That scene isn't mentioned in any In Thy Image
/The Motion Picture
treatment or script of which I am aware.
