I am kinda sad you didn't include "Mustang" on you list...
It's on there. Check out NX-18.
--The NX-13 thing. Superstition? Enh. Maybe it would be better to say that the superstition was dead, but ended up being revived after numerous dockyard problems while building (fires, deaths, explosions, failures of systems, etc.) & the eventual unexplained exploderation of the ship during warp trials off Pluto. Or..something. That way it's a concrete reason rather than something that only exists in Anglo culture.
I was debating whether or not to include that, but I figured that since the fear of the number 13 has been around since at least the time the Code of Hammurabi was made (it specifically omits the number 13 from its list of laws) around 3,750 years ago, that we probably won't be getting rid of it completely within the next 150 years.
It's also spread beyond just Anglo cultures. Chinese buildings will often exclude the 13th floor (like many buildings in Anglo cultures do) as well as any floor with the number four. So you'll find buildings with no 4th, 13th, 14th, 24th, (and so on) floors, like in the Shanghai building below.
In many Spanish speaking cultures, Tuesday the 13th is considered unlucky just like Friday the 13th is here.
And since the concept of luck and good luck charms is obviously still alive and well in the Trek universe (Eddington carried his "Lucky Loonie" Canadian dollar coin amongst other examples) then the concept of bad luck should be as well.
Plus, even people who don't really believe that the number 13 actually represents evil or bad luck will still conform to it sometimes out of a sense of tradition or fun. Building owners will still skip the 13th floor even if they don't believe it, because they know their chances of renting the space will go down.
But mainly I just included it as a fun little reference to break up the list.
--The "Dauntless" renaming. I know you're trying to tie in with "Hope & Fear" as well as whatever ENT episode it was that showed that design fighting for Starfleet in the 26th-century...but...I dunno. Why rename? And were the other early ships renamed as well? If not, then why not? Why just that one? Especially a ship that had done so much & was so well known (at the time, at any rate).
I figured it to be something like retiring the number, jersey, etc. of an exceptional athlete.
I didn't really like or find any logic in the idea of the NX-01 Enterprise being retired completely in 2161 after only ten years of service, yet according to Riker and Troi's personal knowledge and holoprogram in the 24th century this was a known historical fact, so I had to find a way to keep the ship itself operational while still retiring the "Enterprise." The Dauntless thing made sense since the Voyager crew didn't question the registry and since the ship did eventually show up as being an actual Federation vessel (in 'Azati Prime') instead of just being Arturis' creation.
Could be that with the advent of the Federation, the name Enterprise wasn't considered valid for some reason, retired, then brought back out to credit a somewhat important ship in the formation of the Federation. Maybe Archer pulled some strings to get it named that way.
When I posted an earlier version of this list a couple years ago, I said that the name Enterprise sounded similar to a Tellarite curse word, so it was decided to rename the ship after the formation of the Federation. Sort of like James Caan's name Sykes meaning "shithead" in the Newcomer language in 'Alien Nation.'
