Are you familiar with Opera Turbo technology or even Amazon Silk Browser features?
If so, you won't be surprised to learn that Google "Chrome For Android" Team is experimenting on reducing data consumption by loading optimized web pages via Google SPDY proxy servers.

This feature still in development is available behind a switch that you can enable by running: 
adb shell 'echo "chrome --enable-spdy-proxy-auth" > /data/local/tmp/content-shell-command-line'
