Well, if that's a crime, I'd have been executed by now.
I particularly like this early design for K7 (show 42):

One of the early Klingons looks like Meshula's McQuarrie class and McQuarrie phase II Enterprise.

An ambitious modeler could do an alternate Trouble with Tribbles with early versions of the D7, Enterprise, and K7. You could throw in a curvy shuttle for good measure.
