I've always considered the 'material' travelled through during Witchspace transit to be something that can't be comprehended by the human (or at least, sentient) eye (or at least, sensory organ). In my mind, ships with a small crew requirement like the Cobras most often use 'Hypersleep', when the ship uses something similar to a hypnotic trance and then a form of suspended animation to while away the hours between departure and destination point. On larger ships with bigger crews, this would be unpractical, it would require that all the crew 'take positions for hypersleep', either going to their bunks or settling in seats and looking at monitors for Hypersleep induction. In these cases, I'd say that the ship's external viewscreens become blank, except for diagnostic screens that repeatedly run on the various vital systems in use during Hyperspace.
So going by this assumption, for a small ship, the animation would be 'eyelids closing' and 'eyelids opening', while big ships would have scrolling data for a few seconds.
Although I agree there should be some differentiation between the Hyperspace and docking animations, I wonder what requirements there would need to be put in place to create a 'cut sequence' docking routine and whether they would work for those of us with less than cutting edge (read: steam-powered) computers.
