This is being done in HCCI research.

What I gather from the HHO believers it sounds like the HHO destabilizes the combustion in gasoline engines. The same effect can be had by adding diesel to gasoline lowing its "octane value" or raising an engines compression ratio.
It is incorrect to call it a destabilization of combustion. It just changes the reactivity profile of the combustion mix.

The problem with mixing diesel into your gasoline is that you are now stuck with a mix optimized to a narrow load range. This is why HCCI is using dual fueling systems to widen the running range.

HHO cannot hope to affect combustion as much as a few percent addition of diesel into the gasoline mix. But, under certain circumstances, it can help to the tune of a few percent gain in thermal efficiency.
