for my use case (generating an interesting H1), using a similarity score would defeat the purpose.

In this approach, I'm looking for the diamond in the rough. It's often dissimilar from the others. With this approach, the diamond can still get a high number of votes.

That approach definitely has promise. I would have agents rate answers and take the highest rated rather than vote for them though, since you're losing information about ranking and preference gradients with n choose 1. Also, you can do that whole process in one prompt, in case you're re-prompting currently, it's cheaper to batch it up.
