IF Discovery does receive a retrofit, what will it look like? What should be changed? What will be changed? And don’t think about Calypso...
Discovery will be retrofitted. It'll be like a classic car on the exterior and in the interior, but modern under the hood. For what I'm talking about, click on this article.
I could see them adding phaser strips (if that's still what they're using) and maybe changing the nacelle domes, but that's about it.
Change the colour to silver and have blue lights over the nacelles. That will make it look more futuristic. I would also make it more curvy with less pointy edges.
^ Well, that’s one way to pull Calypso into the overall narrative, I suppose. Park the old Discovery in a nebula, cross deck over to the new Discovery and zoom off to new adventures. Cheers, -CM-
