Regarding On The Nose, of all the playings that we've witnessed so far from fan records and TBE, the only sports that have resulted in wins are baseball and basketball. That game could have easily kept those two sports, added hockey and soccer where you hit a puck with a hockey stick or kick a ball and try to score a goal, and maybe keep football as well due to its popularity. Darts was just too silly and Bob even had trouble popping the balloon and I find a sharp-pointed projectile a bit too dangerous, while tennis was basically a more difficult form of baseball where you needed to hit a racket. With that suggestion, you'd have each of the five major sports represented. It didn't have a horribly low win percentage after taking out those two suggested sports, and would find that striking from ground level like Hole In One wouldn't have been too difficult.
I second/third the Walk of Fame suggestions that it should be for a car, like More or Less. The only change I would to remember that this is the Price Is Right: replace the "Range" cards with "Difference", where you need to come within that difference without going over, by simply converting the current ranges and doubling them. The autograph books were constantly replaced, so they easily could have just but the game on a bus during announcer tryouts, then return it to the rotation after Rod Roddy got the permanent gig. It just took way too long to play for a non-fee, non car game, and its a shame that it was retired, since it had a unique cue to introduce the prizes after "That's Entertainment" was dropped, based on a couple of the Temptation SP cues.
Trader Bob should have taken "Don't show us the price!" literally, like Alfonso said. Balance Game '84 is my least favorite of the four, where you can often tell a loss is coming after the third or fourth SP has been selected. They could have reworked it like a combo of today's Balance Game as well as Swap Meet, where you're shown one SP on one side of the scale (with the ARP revealed unlike Swap Meet), and three more on the other side of the scale, where only one of the prizes would come within $5 of the first SP. Like Vend-o-Price, you can have a fee game that involves only one decision and make the show move along.
