Just thinking out loud here: How much is the gain from consecutive ranges? I believe HashCat does in fact not use consecutive ranges even for eg. ?l but instead sort them after some kind of probability order. This would be even more useful with ?a which should probably start with some lower-case letter and end with "~" or some other less used character. I have noticed that when you use a large mask like ?a?a?a?a?a?a it takes quite a while before first crack because the "msb" part starts with seldom used specials.

A compromise would be to use smaller consecutive ranges within a mask: ?a could be defined as eg. [0-9a-zA-Z -/ :-@[-`{-~] but maybe you can't take advantage of them being just "partly" consecutive?
