Are the injectors running static (i.e., 100% duty cycle)? If not, it would be a lot easier to simply add more injector pulsewidth (or fuel pressure) than swap injectors.
Also, what is fuel pressure doing at WOT? If it's holding steady or dropping only only a touch, then more inj pw (if available) will help. If it's dropping a bit, then more fuel pressure won't help as the pump is not able to keep up with demand.
