OK I was playing some time ago that "what if Luke didn't destroy the Death Star, just damaged it and what if in E6 they were only repairing it ? ".

I'm curious to see your final product

That sounds like a good and interesting idea; I'd probably try that if I was going for a trilogy or something like that.

However, since I'm aiming for just one movie in the end I only want one Death Star battle (otherwise it may seem redundant and also just too long of a movie.) I may use some of the awesome dogfight footage from Adywan's ANH Revisited as long as it doesn't look too out of place intercutting with ROTJ footage.

In a multiple movie setup a second DS battle makes sense, because if you have an awesome weapon of doom and it gets destroyed or damaged, what would you do? Look for flaws in the original design and then rebuild/repair it, of course! But that just doesn't fit with my aim in this particular project.
