There is no need to adapt WP QUADS.
Google AdSense is officially recommending the use of "text widgets" to copy and paste the ad code from the google analytics dashboard into your WordPress site for people who were using the Google AdSense plugin previously.

From a technical viewpoint WP QUADS is not doing anything else than taking the ad code and inserting it in a container. This can be between your content or as part of a side bar text widget.
