This looks like an amazing project, and I'll be waiting eagerly, as will many others I'm sure.
I've a question if I may: you mentioned far earlier in the thread that you weren't using the Kelvin design, because its a pure Abrams thing. Since you are using several designs that are also Abramsverse esque - albeit with TOS Nacelles and other details - would it not be possible to modify the Kelvin design slightly? Stick a new nacelle in, get rid of the window viewscreen and call it a refit? That would be a simplified way of describing how the other ship designs were modified, I'm certain, but could not the same principles be applied? Especially if you don't use the actual USS Kelvin.
Other than that, I look forward to this film. Good luck with it. :-)
