the wings must stay - and i think the two vertical are good for a destroyer - while you can put 2 horizontals to the bigger versions like BC or BB.
the wings are what make BHG ships BHG. - ... since these ships are allmost only one big vertical wing + cockpit + a small thruster. - and personally, i like the wings in the back of the ship.... the wings are in the back on the hammerhead, too ( for what you call a back there anyway )
