They did? The Andorian warship was introduced on Enterprise some ten months before the Nu BSG miniseries premiered, and there is more similarity between the Andorian warship and Nu Galactica than with classic Galactica.
So John Eaves (the designer) says.
Another, much less thin design John Eaves proposed for the Andorian battle cruiser was shaped like a rocket and had two distinct inspirations: a World War II seaplane and the Battlestar Galactica, the reimagined series of Battlestar Galactica starting to air about the same time as the Andorian vessel was being designed. "I think subconsciously the main body is a little bit of the Galactica flipped over on top and on the bottom, with some weird looking engines."
