a pretty significant downside though. all quadrilateral diaries ive read have not gone well, and the patient suffered immensely compared to just femurs only and regretted it

It may be safe but it is extremely difficult and I would just do Femur first, then one year later tibia

If you're a girl I highly recommend you settle with just 6cm. With your starting height the ratio of how much you can add is significantly less. If you were born a female than with sexual dimorphism your legs are naturally longer than your torso already. If you go through with 12cm you're going to face some potentially severe biomechanic issues imo.
