That would work, and in fact, doing both the femurs and the tibia for a combined height gain is probably much better for body proportions and biomechanics (if that matters to you, some people just want the extra height, which is also totally valid). My recommendation: Lengthen you femur by 8 cm, and then the tibia by another 6 cm (8 cm is a little extreme, since the Achilles tendon is a little less flexible). This means a total height gain of 14 cm, leaving you at 189 cm, which is a very good height height in any country, even the Netherlands. It makes you tall and attractive, without looking like a lanky. Many Models and Actors have a height of 1.88-1.90. Good luck and enjoy!!!
