Plausibility does not necessarily equal surfaces filled with lots of touch panels and/or switches and buttons. That may provide a certain sort of visual interest, but not one that is stylistically in keeping with the original Star Trek, which employed reflected and colored light instead of busy-ness. To be plausible, make it look magic, but to the characters, as ordinary as the transporter did to Kirk and Spock. There are so many ways the exact same design for sets from the 1960s, built with materials suited to HD and 3D presentation, could be made to look mind-blowingly magical.
- Have the buttons shift using "Terminator-esque" liquid metal technology.
- Have all the viewscreens not only be capable of holography, but touch holography.
- The hard, sharp-edged surfaces? Show how they are made of smart materials that soften when suddenly impacted and then instantly re-harden.
- The chairs could float off their pedestals and shape themselves to the person's body.
- Cognitive interfaces.
- Uniforms as soft as velour but tough as canvas and as warm or cool as need be.
Etc etc.
On the surface, it would look the same as 1966, but once you let it work, it would be seen to be something else entirely. The challenge is how to portray this stuff in a dramatic context. Ordinary, functional, magical, pertinent, simple, DISTINCTIVE. Not a rehash of every SF show or movie since Star Wars, but a reimagining of the original Trek within the strict boundaries of the original Trek.
That is what I mean by yet another lost opportunity.
