I would also like to point out that Moore's re-imagined Battlestar Galactica show with all the radical changes he did to the story and characters still kept the original design of the ship. I'm guessing it was updated a bit but overall its basically the same design that they used in 1978.
No, he didn't. The Galactica only has a barest resemblance of a similar shape. The two ships are nothing alike.
