:%s/\<\([A-Z][A-Z][A-Z][A-Z]\) \([A-Z][A-Z][A-Z][A-Z]\)\>/\1,\2/

This assumes that there is always a single space between the words
which you want to change into a comma.  If not, you would need to
replace the space above with something to match whatever might
be there.  If you do a lot of this, you might want to put the
ex commands in a file and :source them.
