Okay. Pretty sure I'm going to do 7 cm tibia and 7 cm femur.
Ultimately it's your call, but I would strongly advice against that much lenghtening based on what I know thus far about the relevant mechanics.
Your wingspan is in the weak 5'4 zone. Given this, your torso may become quite conspicuously "stubby" at 6', let alone 6'2. My advice is to take pictures of your body and simulate lengthening with "photoshop" type software so that you can see roughly how you would end up looking.
If I were you, I think I would aim for the 5'10-5'11 mark and nothing above it. It's an "OK" to good height almost everywhere, you will save a lot of time and money, and your arms will look more proportional than they would at 6'+. Perhaps you're willing to sacrifice your proportions and mobility in order to become properly tall, but consider it carefully before making your choice.
Perhaps I shouldn't be the one talking since I am betwen 5'10-5'11 and seriously considering lengthening myself, but given that my wingspan is well over 6', I would end up looking more proportional at a slightly taller height. In any event, proportions aren't everything--possibly you will find that you are totally satisfied with how you would look at the full 6'2.
Grab a tape measure and determine a.) your biacromial width (bony shoulder width, laterally from acromion to acromion) and b.) your arm length (from acromion to edge of the middle finger, arm pointing towards the ground). These measurements may tell us more than just wingspan.
