A deeper rear end won't do anything to help this.
At least not enough to justify the cost and inconvenience of roaring around like an old Army Jeep the rest of the time.
OP indicated the real issue was running at high RPM is uncomfortable (not harmful...uncomfortable)
So by that I assume, it's not an issue of being stuck all the time in 1st gear struggling at 15-20mph climbing hills and they can't get the engine up into the RPM range to put out lots of HP.
As long as there is room to drop down more gears, the rear end isn't the limiting factor, so unlikely it would do anything to allow better hill climbing.
OP indicated a 2015, so I'm guessing a 6 speed transmission...If it was a 1980'something with a 3 speed, I might give a different answer based on more specifics.
