If they did a calendar with images of novelverse characters, I would buy that thing in an instant. Especially if they had Vanguard, Titan and Voy-R 2.0 characters.
Off on a slight tangent, it would be good to gather images from the novelverse together somewhere. I know there's stuff around, but an getting pictures of both ships and characters from the books together in one place would be a great resource.
I'd be particularly interested in Vanguard, The Voyager Fleet and ships from the Enterprise novels, particularly Christopher's RotF.
Someone a few years ago made a thread in Trek Art trying to design the cargo ship from The Buried Age which looked pretty cool, but I think the posted gave up because of the level of nitpickiness from Christopher.
