We're actually talking 2358 here. If you did try to do a design for Cleopatra's Needle, I'd certainly be interested to see it. It'd be nice to see what the state of the art for civilian Federation ship design might be like in the mid-24th century. It would probably have some design similarities to Starfleet vessels, given a common culture and technology, but with a fair number of differences too, since it wouldn't be designed for combat. An interesting challenge, to come up with something that looks Federationish without being Starfleetish.
