My suggestion would be to keep the current scheduling of 5-7 programs on ABC during each of the "sweeps" months, but bring back about 10-15 of the recent top winners from the daily syndicated version as the contestants for these programs as they once did for a "Tournament of Champions" during the "regular" Millionaire's prime-time run on ABC.
These contestants would be on for the entire series during that particular "sweeps" month and 10 of them would start out in the "Fastest Finger" chairs (which were eliminated from the current syndicated version). Winner of the first "Fastest Finger" question plays the game, and then his empty FF chair would be filled by the next player in line for the next FF question, etc.
I would also make a slight change in the money progression and the guaranteed "plateau" amounts as follows:
$1,000
$2,000
$3,000
$5,000 (plateau)
$7,500
$10,000
$25,000
$50,000 (plateau)
$100,000
$250,000
$500,000
$1 million (plateau + 2 additional lifelines)
$2.5 million
$5 million
$10 million
(A little more logical progression, in my opinion -- I feel that with the current amounts, there is too big a jump from $100,000 to $500,000 from the 10th to the 11th question in the stack, while the current progression tends to run too slowly up to the $100,000 level.)
I'd also keep the current question difficulty -- more logical for "returning champions."
