In the history of Star Trek, I can think of no other time that any vessels were designed like this during the TOS time period. IMO, This should have been a next retrofit Enterprise NX.
That's because at no other time in the ORIGINAL timeline did they look like Abrams' Enterprise. This is an alternate timeline with alternate expressions of the development of the same technologies. It's right there in the dialog and it's also backed up in Star Trek: Countdown.
The original Trek Universe is still there, the Mirror Mirror Universe is still there and now the Abrams' version of the Trek Universe is there. What was the story where Worf was jumping from universe to universe and things were different in each? Same idea.
Who knows...Maybe they will take the Star Trek franchise in the direction of the Alien and Predator franchises.

This actually reminds me a weird idea about a Predator/Trek mix I had in mind for a comic...If they put Ripley in the mix, the entire Star Trek crew is screwed. A phaser is no match for a pissed off female with a pulse rifle or a Predator with an oversized weed whacker and cloaking device... LOL
