Hey Yellow, I'm just curious if you have experimented with wearing lifts after your first LL. If so, did the additional height gained by the lifts make you feel more proportionate and "average" as you expect from a second LL?
Also, I happen to agree with those that recommend tibia instead of more femur. If you have tibia done in two stages instead of one, you could be back at work in a month after surgery for the first leg, and have the second leg operated 3-4 months after and take another month off then. Your work should be somewhat understanding of you for taking the time off if you mention medical reasons (like correction) for your absence, and one month absence is not a lot.
I know most of us want to plan every aspect of our lives, and believe that we are in control of our destiny.......but the truth is that life can change every passing moment without warning, and all of a sudden you get a phone call like "I'm pregnant!" or whatever...... My point is that we can only control what is directly in front of us, and if you should happen to need unexpected medical treatment, your work should be somewhat lenient and sympathetic towards your situation.
As for the risk factor of doing tibia LL, that is entirely up to you to decide...... just my opinion.
