I really like this ship. I can see when it might not have been "sleek" enough for TV, but it's a nice background design.
I wish I had *any* skill for art or design...when I first saw the Intrepid concept, long ago, it gave me an idea fro a similar ship, but built using Excellsior components.
Lower the saucer (by getting rid of the neck - well, shortening it significantly) and flip the nacelle arm thingy upside down. Always wondered how that would look. (Maybe add some elements from the Centaur design from DS9...)
Just an idea I had.
I guess something similar-ish exists...but mine wouldn't be *so* different. And really, I'm not sure what would be all that different about a ship based on my idea would be from a regular Excellsior Class...but the Intrepid prototype made me think of it...
