I think it's hard to get those Trek iconic images out of my head when thinking about it. But we could also use the design principles when the ship model design was commissioned. There should be guidelines.
Since it was your idea, how about pretending you're Gene, and give some things you don't want to see (other than what we have already)? I'm going to sketch some ideas at work. Lots of little sketches LOL. Wait, did I say at work? I mean at work.
