You need to be more concerned about 0 to 30 pound range to make sure that you are maintaining an acceptable minimum of oil pressure.
My 30 pound gauge is pegged most of the time. The only time it drops to between 20 and 25, is when at idle on a hot day. It pegs at 30 as soon as I step on the gas pedal.
I don't think that it is worth the effort/expense to make the swap.
