For starters it looks like a Lost era design.
I think the two necks are uncomplimentary, it looks like a hasty field repair job thrown together for a last stand somewhere. Klingon physiological redundancies aside; it just looks unfinished.
The design would benefit with armor over the two necks or better yet, a (marine, fighter bay) pod of sometype that would completely fill the space occupied by the two necks.
Just my two cents.
