There is already memcached_gzip_flag, which allows to add 
"Content-Type: gzip" based on flags a memcached item.

http://nginx.org/r/memcached_gzip_flag

And even gunzip module which allows to gunzip such responses for 
clients which doesn't support gzip.

http://nginx.org/r/gunzip

Not sure why you want to introduce another directive for this.
