no, go on, have fun! it looks great, but keep the power requirements in mind: you might have to add another set of turbines (and for shafts this long, integrated electric drive would not be an bad idea
)
I have some doubts about an twin gun fitting in that unit, though
and I also doubt the forward 2 VLS cells would be different in position, for construction reasons, unless you can show me an real world ship with an arrangement like that? (note, for 2 blocks a bit apart from each other it makes sense, but as close as this I doubt it)
