Ok, let's not argue creativity any longer, because that is where the "I don't like it and therefore it must be revised if I'm allowed to create Star Trek for Paramount" argument can work, while I prefer the analytical playing field of "I don't like it but that is what's onscreen and in official sources." As for the initial question:
The answer to this remains, "There is nothing about it which disrupts the existing canon." If one is allowed to be creative, the discussion can obviously go into any number of directions.
With the slick looking, more advanced NX class Warp 5 cruiser, can we really take the Warp 7 Daedlus class ship serious now? Obviously, created WAY before the NX and an early version/forebare of the Constitution class. It is so out dated looking, and fragile, that to shoehorn it in between the sleek NX and the classic Connie, is a bit hard to swallow. Yet it is cannon and is an established class.
