If you really incite that theory that demonstrates patients can not go beyond 15-20% of bone lengths then first there are already outliers and 15-20% can just prove most of men can accomplish option 5 unless you got really really short legs. If you really want that theory to make sense then option 5 is even totally safe bc 16cm does not go beyond 15-20% of most men's total bone lengths.
The "theory" is not mine, it is defended by many surgeons in scientific articles and, by the way, it's of course present in Paley's own limit for tibias of 5 cm.
Second, the percentage limit is in regards to initial each segment or limb length, not the person total height.
Third, you can always find exceptions and surgeons willing to do whatever you pay for (including Paley).
Fourth, you are free to think and dream whatever you want. Being or feeling short sucks.
But if you want to consider CLL seriously and optimise safety, do some research (medical literature, diaries in this forum, experienced users,, veterans outcomes, etc.), beyond any wishful thinking and surgeon's propaganda.
