Understandable, it’s a great cue and works well in the scene. However, in my mind, it had to go. First because it’s the second time we heard that track in the film (trying to reduce this kind of repetitive tracking), and second because this is the birth of Vader - let’s hear his march.

Honestly, I like both, and they both work very well for that scene. I think the best approach would be a compromise. The Imperial March only really kicks in at the end, so how about leave it there, but use the clone march for the rest.
