I'm not a fan of retconning designs. I'm really not. The whole idea rubs me up the wrong way.
That said, this ship is absolutely friggin'
beautiful. She is expertly built, her components are in proper proportion to each other (managing to completely avoid the horrible blockiness of the 3d renders of larger and smaller SFB ships), and she just looks
right.
Although I do agree that the bussard nacelle caps would look far better in that faded, white-dappled reddish pink that the latest TOS Constitutions are wearing.
While she will never be in my "official" Star Trek lineup even as a super-duper top-secret highly-advanced prototype, I still want her to take for a spin around the Klingon Empire
Hmmm... maybe I can incorporate it with a technobabble reason... like the
Dauntless NX-01-A from VOY. A cunning plan by the Blackadderites to trick an isolated Fed crew...
Hmmm...
Additional:Since you're retconning the
Defiant, what would you say to retconning all the late TNG/DS9/VOY ships into highly detailed TOS-style ships. Like a theme pack for SFC? Redo the
Akira,
Norway,
Sabre,
Steamrunner,
Intrepid, and
Sovereign classes the same way you've remodelled the
Defiant here?
