I'm glad you took the time to say it, as I've been hoping for a more cohesive Coruscant storyline to justify the argument to include it. I honestly still don't agree, but I like your concept and it's clearly been well thought out.

Though there are other reasons, my biggest reason for not using this idea is that it in many ways reduces the tension. We're not talking about an impending threat that must be eliminated while weak. We're talking about what could be simply a massive attack, timed whenever it becomes convenient. To me, that just dramatically reduces the looming danger the Rebellion is in, having to strike during their darkest hour. And on top of that, destroying the Imperial Palace is not nearly as climactic as destroying the Death Star.

But don't let me discourage you. This is a place for creative discussion, and I'm sure there are others that like your perspective. I hope you'll stick around and continue to fight for your ideas :)

This is how I feel as well. It's not as though Coruscant will be flying around and blowing up other planets. The rebels could leave it there as long as they wanted.
Plus, it's not just the imperial military living there, right? All of the citizens of Coruscant who lived there before still live there.
