I was just looking/hoping for a little more reasoning as to why they would use the name of that race for their cover story. Humans and Vulcans don't look that much like K'normians.
Neither do Bajorans. There's no law that says a person of one species can't buy or operate a ship built by a different species. Heck, we've seen plenty of instances in the shows where the same starship model was recycled for different aliens' ships, like the Arkonian warship from ENT: "Dawn" being reused for Xindi and Tellarite ships later. So there's precedent for the idea of one species buying ships built by a different species.
