I would say Crosshair. Harriet cares about her team, who she sees as more than just coworkers. Crosshair on the other hand, hates most clones. "Oh, I don't blame you. I would have left him behind too. After all...he's just another reg."
Oh, Tech could have disarmed it no problem. I think Echo could've helped too, if the bomb had a hole input for his right arm.
The Bad Batch is the opposite of the Ace Ops, so I would say yes. They're good people, and I she a feeling Hunter knows which fight is worth fighting. They could actually see their blind loyalty as behavior of the "regs", maybe even after Order 66.

I would love to see Leela and Romona. Since Gallifrey is gone, Leela would have been impacted and I'd like to see her final moments. And nobody knows what happened to Romona, so I would like to see her again. Also, Susan would be nice to see again.
I wouldn't say it's overused. The music is about hope and serenity, which is what the light side of the Force is about.
As for the vehicles, I would LOVE an AT-AT. They're large and slow, but they're strong and a force to be reckoned with. An army of them like in Empire Strikes Back would make the opposing side helpless.
