I know this is going to be your ship and all, and I'm sure you're fully aware, but don't make it total SNAC food. All those things sticking of it makes it considerably easier to hit.
Nah, a Nyx would be if the fins remained separate from the hull bu stuck close, maintaining some space in between.
Even then it wouldn't really *be* a scaled up Nyx, not even close if you are obsessive for detail...
Anyways its not my ship, I just wanted to visually communicate my opinion.;)
