I find the approach very interesting, but the main problem I see is that it is based on whether the Eva representation of the character is a vowel or a consonant. Given that the Eva representation is essentially arbitrary, this is likely to end up with a result that does not differ much from 'chance'. I believe that this is what @obelus has demonstrated.
It might be worth doing the same thing, but classifying the initial characters by one of the attributes of its shape.
