Jim...in small amounts, 2-4mm, I don't think it will effect the hips and center mass.  I believe this only changes the angle of the foot to the ankle. The lower leg and stance should remain the same. However, the amount of or lack of up and down travel of the foot could play a significant role in this consideration.

I actually raised the front of my zeppa board 1 degree using 4 pieces of duct tape. In this position, I felt my forefoot had better contact with the bottom of the boot. More specifically, I could feel more even and immediate contact beneath my toes.

There are so many variables depending on stance, individuals flexability and "performance awarness", (noticing a result which is either neutural, positive or negative).So I agree, go cautiously and in baby steps for anyone looking to play with this.
