I believe ewest already proposed this on another of today's Brettski threads, but if you can add HSB as needed, I think you could make BG, YP, and SMB work with the additional predator.

As a fallback, introducing LMB should get any runaway species (unfortunately, including SMB ) under control given time.

What did you decide on for forage species to start out with? Just FHM? Any GSH or Gambusia?
