I don't know what types of injectors are used and what their flow rates are, but there could well be problems with this approach, because the secondary injectors should have more flow than the primaries and some injectors don't work well when the duty cycles are very low, which they would need to be down low in the rpm range. The whole premise of the motor was to make a lot of torque down low and yet have the air flow and fuel to make max power at the high end of the rev band. The approach you are thinking about will probably reduce torque at the bottom end and might add some to the mid-range. The top won't change at all. I would think trying to open up the secondaries a little sooner and retune would be a better approach.
