“As you wish” - Sounds perfect.
“He’s not worth anything to me dead” - Sounds good to me. If I’m being really nitpicky, I feel like the emphasis would normally be on “dead” rather than “anything” - like, “dead” would have to be pitched up slightly - but I don’t think I would’ve noticed if I wasn’t deliberately looking for seams.
“He’s worth a fortune to me.” - I think the problem here is vocal quality, unfortunately, rather than something digital. “What if he doesn’t survive” is quick and full-sounding and matter-of-fact; but “He’s worth a fortune to me” sounds softer and slower, kind of raspy and whispery and sinister. Maybe speeding up the line a little will help it to match better? But god knows I’ve had to scrap a bunch of potential line replacements myself because the vocal quality didn’t match.
