Sure it will. Just rename /bin/gzip to /bin/gzip.real, and create a shell script 
/bin/gzip that looks like this:

#!/bin/sh
exec gzip.real -9 "$@"

You're the sysadmin, so you can do this. (And if you were not the sysadmin, you 
wouldn't be able to edit any global configuration file either.)

The GZIP environment variable leads to functionality and security problems, 
which is why it's being deprecated.
