A few tips regarding BC modelling:
For a ship like this, you can easily set the polygon limit to around 10-14k. The CG Sovereign is around 13k, and there have been ships released with more then that. Of course, part of the limit of how many ships you can have at the same time is due to the polygon count, another part is the texture sizes.
I think the general concensus is that the saucer textures are 2048x2048 (I think DJ Curtis's Enterprise-F has 4096x4096 saucer textures), and that other parts of the ship use 1024x1024 textures.
Would love to see this ship ingame
