Yeah lets be honest, they'd probably change the whole damn thing if they wanted to make a show in that era. Longer nacelles, curving struts, new bridge dome to accommodate the gigantic bridge window, fatter impulse engines etc etc. All new interior sets that "homage" the original should be a given by now, it's just what they do.The Interiors look ENORMOUS. Compared to TMP. It will have to have extensive restructuring. Don't think they wouldn't do it. Because they would.
Early on, I had this niggling fear that the appearance of the Enterprise-C in S31 would be a brand new visual headache for everyone, but we were spared that fate. (We suffered in other ways)
It doesn't matter what WE think looks good, it's what they think looks good. If they think our favourite ships look outdated and ugly, they would change them.
