Here\'s a notion: Winners of the first two games play something similar to the qualifying round of Password All-Stars. Two or four celebrities take turns giving a list of things that fit the subject. The two civilians play against each other, buzzing in to guess.
Six (or ten) subjects, each for an amount of cash--the structure of consolation money in the end game.
Penalty options for wrong answers: free clue(s) for the opponent, or opponent takes the subject by default, or wrong guesser has the dollar value deducted (a la Jeopardy!).
Player with more money plays the returning champion in the front game, winner going for the grand prize. Could be a pyramid of ten subjects in 1:30.
This breaks up the hour without adding anything out-of-place like the Chain Reaction end game. Maybe here, the subjects aren\'t shown to us viewers, putting us in the opposite chair. It would also offer an opportunity for new set pieces. Hopefully moving ones.
