I doubt you will really be able to tell the difference from what calculates out to be 3 IBUs. Studies have shown that it takes about 5 IBUs before you will notice a difference.
That said, in the case that you were going to alter the amount, I would suggest adding the desired amount of flavor and aroma hops, determining their IBU contribution, then determining how much bittering hop you need to achieve your desired overall IBU rating.
