You can cobble together a Federation class by using the parts from P81's connie and Atra's Ascension, shouldn't be too hard a kitbash to do. 
Lol thats exactly what i did with the "Alternate Federation" already 
I put 5 dreadnought variants up on SFU, just do a search for "Wolfsglen" and check all 3 boxes for author/filename etc and it will list what ive put up there.
There's a few subtle differences.. I wanted to match the Federation DN's shape.. as well as have a single impulse engine and manifold, and a single torp launcher, forward only.. I also added the SFB-ish droneracks at the rear of the torp launcher just like I did for the CVA. ..
.. also, redid the textures for NCC-2101 instead of NCC-2101A (which is fine, since it's different

)
Although, you're still in the credits Wolfsglen. After all, I started from what you released.
