Yes, but there's only a minuscule difference between the moustaches of Thomson and Thompson, which, unless you were an avid fan of Tintin, probably wouldn't even notice in the first place.
I for my part wouldn't recommend customs--I personally dislike them and unless you are very, very good at making them (and have a machine that can print on LEGO heads) they usually look highly crude and amateurish. It's LEGO in any case, so there will always be some inaccuracies, and frankly this is one of the least noticeable ones so it probably wouldn't be worth it spending lots of time getting a tiny detail like this right.
