Have so big, complex and different imperial ships in the battle might create confusion.

Not that i dont see a particular reason go so deep into putting more ship desings in the battle but i cant even think the amount of render and compositing part. Very few can support so big scenes and compose them.

I would love giving executor a reason to be called a superstar destroyer and not just be a big ship just standing there..(maybe a big gravity gun that cant allow ships to escape.

Besides allways you have to establish why or what is this(new ships) and what they do so special. (i guess star wars failed to deliver what Ywings are and Bwings as well)
