I would not say this is excessive for a disc/drum system.

What many folks including seasoned mechanics don't catch is that pedal height, when you're sitting in the shop, is really based on what you feel is the right amount of pressure applied to your leg by the brake booster while pedal height while driving is much more dependent on how quickly the vehicle is stopping.

There are two tests I usually use in this situation. 1) walk away from the vehicle for a period of time and forget about the way the pedal feels. Then get back in and repeat the test to see if alarms go off in your head... "Holy smokes! That's bad!" 2) If the first test is a pass, drive the vehicle. If it's stopping well with the pedal at a greater height than what you were measuring in the shop, the pedal is fine. No further worries are necessary.
