Yeah. All depends on how you focus this edition, if you want to make something with a modern looke, as "how ST V would have looked with modern VFX" or if you want to make some kinf of retro restoration. I think they would choose the 1st option as is easier and could be more appealing for general public. The bad point about that is it could not fit very well between the other classic ST movies if it has a CGI Enterprise. As i said, the look of modern CGI does not pretend to be realistic.

Discovery shoot looks like a Star Trek online graphic. ST III shoot looks real because everything is real. And the touch feeling is evident when you see that scene. The models have weight and dimensions sense that makes them look much more realistic. I am not saying CGI is crap or anything, just that the models worked perfectly in the classic films and no new CGI ships have looked better than those models. That´s part of reason about why scenes like the one with the Enterprise in TMP or the Reliant vs Enterprise battle are so amazing. So... i would definitely do a ST V recovering the Enterpise A model and film with it, adding CGI when neccesary, specially for exterior shoots like the ones with the barrier and Sha Ka Ree. (Modern use of models is impressive as it was proved in the new Star Wars films that made use of real models).
Good modelwork will even improve the best CGI (and that new take on 1701 looks rather good, regardless if it's "25% different" or not.)
The question is, does the CGI still sell the scene in way practical/model effects can not? Exhibit A is TOS-R. "The Doomsday Machine", "Space Seed", and others have CGI that's clearly CGI, but the little details thrown in with asteroid bits bouncing off of ship hulls, dispatching the Botany Bay, et al, more than make up for it. IMHO. Granted, those stories also have stronger if not wildly different plotlines... again, IMHO - YMMV.
Also, TMP showed close-ups of people next to the ship or even looking out of a window - something not really done much before, or since (oddly). That alone imprints "feels real so it must be". But TMP's models were so good and looked realistic to begin with... the amount of CGI shading to render, especially with the varying amount of lighting everywhere... the episodes are expensive enough; to give them that much more rendering time is silly. The new 1701 looks robust enough, and effects only accentuate and complement a story. And not be it. This isn't 1990 anymore when VHS copes of "The Mind's Eye" were selling like hotcakes and watched three dozen times per year. CGI isn't that new or novel anymore.
