Doubtful. Describing it as "The Great Experiment" and giving it an NX- classification point toward it being a new design meant to test the transwarp engines for viability. That such a design would become ubiquitous 80 years later points toward the design being sound enough that even though the transwarp engines failed, the ship itself was workable. Give the testbed a reliable engine system and outfit it for standard duty, and you have the first of a new class of starships that become the workhorses of Starfleet for decades to come.
