It would be possible, but it isn't feasible to gzip single log entries.
(Which such a directive would do I assume)
However, you could do something along the lines of this, which would
yield usable compression factors:

mkfifo /var/log/apachelog.fifo
(while [ ! -f /tmp/stop_apachelog ]; do cat /var/log/apache.fifo; done; rm -f /tmp/stop_apachelog) | gzip -c > /var/log/apachelog.gz

Now when you want to rotate the logfile, you create /tmp/stop_apachelog,
wait until it no longer exists, rotate the gzipped logfile and
restart...
