It sounds cool, but if you don't know it's already associated with an evil authoritarian empire. A second one can't really do more damage. You can still like the song.

To be fair, Star Wars is a dystopia. Authoritarian Empire rules, with troops willing to vaporize entire planets to quell ragtag bands of protestors who eventually go military in their operations. There’s your organized antifa, the rebels.

It’s easy to parallel it because it’s an established archetype in life and lore. Authoritarian regime vs underdog rebels.

But with magic.

I like entry of the gladiators for this purpose

We need a "...Valkyries", that's been arranged to sound like 5th grade band. Like a Wagner Shreds video. That would be perfect for this entire regime.

That would be nowhere nearly as effective.
