It's hard to tell with cloths on, you could hide a lot of it by wearing your pants low for instance. Although 180cm seems a bit much, -10 wingspan and 14cm's of lengthening will probably result in a disproportional look.
Most of us wanted to get +10cm's in the first place but the more you read here the lower your goals get.
Even one surgery is painful, time consuming, expensive and probably bad for your long term sportive performance. Only a few people do two surgeries.
You could do 7-8cm's with internals, it should be much easier to hide than tibial lengthening. 173-174 should definetly be a large improvement.
