Shire would be a great addition to the ID, as a slight offtopic.
I can invision another ship along the lines of the Clydesdale-Percheron evolution, if one were to take the shell dome, enlarge it slightly for 7 turrets (two bottommounted) with a pair of the circular bret engine pods protruding from the rear (these under and inside the cover of the shell, as opposed to where they are on the Perch, slung out in the open). The forward space under the shell is cargocompartments..
