Not at all. Shane's Johnson's now out-of-print Mr. Scott's Guide to the Enterprise came up with a very good idea of how the incorporation of new systems led to compatibility problems that required changes in the ship's design to accommodate them. It's definitely plausible that after awhile, a decision was made to redesign the entire vessel. Basically, making it a refit that spiraled out of control.
I'm not saying that the explanation is bad, C.E.
I'm simply telling you that the design of the model makes it physically impossible unless they dismantle the whole ship.
However, if you assume it's just a retcon, the problem evaporates.
I have Mr. Scott's Guide to the Enterprise, by the way, and it's a very nice collection of deck plans, though I don't know how accurate they are. He gets the dates all wrong, however, as he's basically making it up as he goes.
