Lynn,
I believe the best place for direct injection would be in about the same place that Mazda ran the "far trailing" plug in the Le Mans engine. It is a possible place, some of the original NSU tests used the trailing plug hole and single ignition. I would prefer to stay with 2 plugs.

How about the injector boss screws into the trailing hole. The port for the injector above the centerline to some degree and the trailing plug is a 10MM body plug instead of the usual 14MM. I would also mill the small hole into a horizontal slot as is done by some racers.
You could be injecting right across the tip of the plug, or even through the plug gap.
You could run the plugs all of the time to keep the gaps ionized. Time the engine with the injectors.
