I'd rather leave EGR alone for that matter. One thing I've been considering is to increase the intake valve opening time, like it's done in hybrids, but with a supercharger in order to overcome the dynamic discompression. It has been done in stationary/industrial and marine engines since the 30s or 40s, and Mazda did it in some version of the 929 full-size sedan.
