I'm not sure you absolutely need producers with suitably placed hearts as much as you need producers with the sense not to screw up a good show when you hand one to them on a platter -- and anyone who's already an experienced performer is going to be three steps ahead in that game.

That said, what might make sense would be to shoot some email off to the TLAPD folks, since they've worked with said producers already and will have a better idea than any of us what the tradeoffs might involve.
