Been thinking of doing this one already... it doesn't take too many modifications to what I did with the "Bubba" Class textures, and I already have the blanks for the saucer regs..
The one thing that I was wondering about this episode though was how badly borked up the Trek Continuity is now... unless the whole DS9 Mirror Universe is just another alternate universe of the Mirror one we saw at the time of Kirk. Which I could easily accept.
(You have Zefram Cochrane making the first warp flight and killing the first Vulcan... which wouldn't have happened unless the Mirror Universe Ent-E had come back in time to fight the Borg, who may or may not have come to Earth in the first place if the Mirror Universe Ent-D hadn't have existed to run into Q... but then Q had been shown to have been on Earth in the past, which means he'd likely have tormented JLP anyways, which could've led to the Terran Empire meeting the Borg, et al).
Personally, I look at it this way. We've seen a Mirror Universe-type interpretation of Voyager, and mirror-Spock's predicition of the death of the Terran Empire wasn't for a while after the time of Voyager/DS9. So I still see the Terran Empire continuing until the period of the Timeships, after which the Terran Empire'd use those to prop itself back up. As long as the Federation exists, I see now reason why the Terran Empire'd not also exist. The death of the Terran Empire'd also reflect the end of the Federation, and that'd not happen until it was replaced with something else, like either a Trek-Prime version of a Section 31 Terran Empire, or else some form of true Galactic Consortium. My view on it anyways..
At any rate, I'll see what I can do towards getting something like this one together soon...
