It won't be much different. Pales are in the 1.040-1.055 range and 20-40 IBU, so unless the recipe targeted the very top of the IBU range, it should be fine. Very few people can tell the difference between 20 & 30 IBU.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
