Why would be doing 16bit reads from fast and 32bit writes to chip be meaningless? I understand you are investigating code density but made the extra condition to use 32bit moves for the writes because they are to chipmem on a 32bit chipmem machine. Your four word-size moves example violates this condition. My code does not and shows better code density and possibly even better speed on some 68k. To proud to admit this?
