By the way, what do you think of also considering d-t, z-s, and g-k (and also zh-sh if such combinations will be… since they are not clusters) pairs the same (not all of these consonants the same but only their pairs; they are paired by voicing)? At least in the ends of words, because of terminal devoicing described earlier. Though considering russian, it would be better to just consider the voiced-devoiced pairs the same everywhere. This will probably cleanse list of possible words much more.
