Yes, we/I did when I was doing repair regularly. It just depends on the thickness of the leather being added. But any thickness moves the foot forward...again, displacing the joint/treadline of the foot. All these after-the-fact remedies are fundamentally desperate attempts trying to make a bad situation less bad...they cannot correct the problem nor are they entirely benign or physiologically neutral.
They are "cobbled together" solutions, no disrespect intended. Sometimes that's all you got to go with. But the better solution is not to dig yourself into the hole in the first place.
