What is it I'm missing? Also - any recommendations on LPFP settings, too?

You can, just keep in mind that is not a free lunch and not linear. A 20% increase in rail pressure does not equate to a 20% increase in injector flow. And asking the pump to produce more pressure will make it tap out volume-wise sooner (just like all pumps). You can do it, just do your usual due diligence and watch all your numbers and see if it helps.
