This is what pgfpro was approaching.

Adding turbulence via boost and heat coupled with lean burn allowed pgfpro to control combustion reactivity. Not to the point of HCCI, but such that you could ignite the very lean ( 30+ AFR ) mixes at a reasonable lead point to produce useful torque. Of course , without the rapid oxidation rates of HCCI we will have to deal with NOx, but I'd rather reduce my fuel use and deal with NOx after-treatment.
