Star Trek TNG Cheyenne Class Dreadnought fan design

So, in case you haven't noticed, I love the Cheyenne Class from Star Trek TNG. I wish they did more with that thing. But hey, I started thinking about how to upgrade it. Dreadnought canon under the saucer, pylons from the Andromeda class, and Galaxy Class nacelles from to upgrade everything from the saucer up while still keeping the same soul. Still no deflector dish because screw safety, right?
