It could get a little ugly, but your best bet may be to mix and match her different lines. That could also get disjointed based on the tone and inflection of her voice.
Here is a line from S1, Ep. 15:
“Maybe this mission doesn’t make military sense. But Kanan is family. And we’ve all lost enough family to the Empire. So rescuing him makes sense to me. I’m not ordering you, any of you, to come along. But you need to decide now. In or out?”
You could find her mentioning Fulcrum elsewhere and get a line like this: “Fulcrum is ordering you to come along this mission. In or out?”
I’ve experimented with making new lines from existing ones before and honestly I don’t think it works to well. For now, I’ll keep an eye out for any bridging scenes that could be inserted and/or hope someone who reads the forum could give me an AI generated line I could use haha.
