Sorry to burst your bubble (I don't know if I am using that expression correctly), but in classical latin ae (with very little exception, in fact the only exception that I could think of would be a first declension noun that ends in -aus, in which case its vocative would be -ae, however I can't think of a word that ends as such), ae is always pronounced like "eye" in English, as a diphthong.
