Idependent runner/throttle blade will only work if there is a plenum connecting all the runners together otherwise there is no common source to pick up the absolute manifold pressure from if you are plannning on using a speed-density EFI system. The other alternative is to common the IR throttle bodies into a common sealed airbox and run a mass airflow sensor into the EFI controller.
This is the one area where EFI is not as flexible as carbs. If you choose EFI then functionality has to take presedence over looks. It all depends what you want - looks or drivability.
