I think this is a good idea; I just pushed new unit test test_similarity() to github which finds such similar words. Right now it identifies ~90 similar pairs in current wordlist, I'll update wordlist tomorrow to pass this test.

I think avoiding words that could look similar when written down would
be a good idea aswell. I searched for words that only differ by the
letters c & e, g & y, u & v and found the following:

car ear
cat eat
gear year
value valve

Other combinations could potentially be problematic depending on the
handwriting style: ft, ao, ij, vy, possibly even lt and il?
