Got around to making another DDL for myself tonight:
I started with a Federation Command Cruiser miniature..
But since I had an extra "upper" nacelle from a Fed dreadnought - I decided to use that:

Then I decided to make the miniature visually distinctive on the tabletop...
So I changed horses mid-stream and went with the neck off of a Federation BCH - including the gun-house.

In this image, you can see the locating holes in the saucer and nacelle, as well as the corresponding mounting pins in the neck.
