I'd love to see the idea explored in greater depth it could make ROTJ something much grander than just a retread of themes already played in the OT.

I loved your earlier mockups Angel I wonder what you could do now that you have learned so much more?

I'd still like to keep the second one as a surprise that pops around the corner once the rebels are already caught in the battle trying to destroy the battlestation they know about.

Going by what Needa says in ESB cloaking devices do exist in the Star Wars universe but can't be fitted on small ships maybe the other Death Star is invisible until it needs to open fire.
