pingback_post _would_ the hook to leverage to do this in a plugin.
pingback_post is given the comment ID; but it gets called _after_ the
comment is added to the database.

preprocess_comment is probably where a plugin should get involved to
solve this problem.  It's a filter that gets executed first thing in the
wp_new_comment() function, and is passed the entire comment data array.
