That question could be two different answers, so I will give both.
Is editing the rest of the legs bothersome ?... It's tedious for sure, especially now, because I have done so many, but not in a specific order... the only way to be sure is to go through them all in a specific order.
Are the skinny legs themselves really that bothersome ? Not to me...
I can not remember the last time I saw them in a game. This may be because I have edited every team I seem to play against in my Dynasties.
