I'm currently in the (very slow) process of creating a full Star Trek conversion for a game called Sins of a Solar Empire set in the TNG future, circa 2400.  A lot of the work I've seen here has sparked many ideas, and I've certainly pushed myself past the limits of what I originally thought was possible as far as my own ability to model and texture.  
With that said, I don't actually own BC, but as a big thanks to this community for all of the inspiration I've received here I'd like to offer up any or all of my completed models/textures as I finish them to someone who might be interested and can convert them to Bridge Commander.  I'd also like to improve my work through any thoughts/critique.  Sins has dozens and sometimes hundreds of ships on a map at once, so I've kept this model to 4600 triangles, plus a single 2048x2048 texture sheet.  I do all of my textures in Illustrator, so if someone would like to convert the ship to Bridge Commander, it's a simple matter for me to scale everything up for multiple high res textures with any loss of quality.
My current project, and also my very first 100% from scratch model/texture job, is a refit of the Norway Class.  While searching through all of the current models in use in the various ST games, I was struck by how low quality the options for a Norway actually are.  Knowing that I was going to create my own model, I decided to throw caution to the wind and re-imagine the ship in a late 24th century/early 25th century refit-style using the colors and design aesthetics seen in the Vesta Class with a few nods to the First Contact-style paint jobs.
I've nearly finished with all of the foundation textures (with only the nacelles left to complete), and then I'll begin adding the remaining details.  
  
***You might also notice a few similarities with Wylie's Proteus Class.  I was actually imagining an incredibly similar concept for a light cruiser/interceptor when he first posted that in August, and I wanted to see where he went with it.  So, I put that on hold and began this ship with some similar ideas.
