Just thinking about the guest judge for the finale...past and present

[aga]

My thought is that the producers have a voice, but I don't see them setting a radically different direction. If two competitors are in a dead heat to win or lose, then yes their input can be the deciding factor.

Also, I don't think that Heidi, Michael and Nina are so pure that they cannot themselves see what appeals to the reality TV viewer and factor what sells into their scoring and deliberations, the producers don't have to lure them to the dark side.
