This seems like such an extreme option just to add a few inches to your height. A more sensible approach might be to modify footwear design similar to platform shoes, but in a more subtle fashion. I imagine something like a thick sneaker sole where the shoe material meets the sole halfway down, so it still looks proportional to normal shoes.
