I really don't think Coruscant would work in the end - the way the movie works out. It would be cool, but I'm not sure what that would do to the tension, having Luke millions of light years away from the action.
On a different note, here's my video mock-up
Keep in mind that it's JUST a mock-up, so don't expect completed/good-looking effects or anything.
It obviously needs some work, but exciting stuff either way. I really love that close up of the A-Wings. Awesome.
Just thinking here. Right after this is where the A-Wing flies into the Executor. What if the A-Wing fired a missile instead?
