Mark's boast would have to take a back seat to Louis Cowan, because Cowan's hangman-style panel show Down You Go had a very respectable prime-time run in the 1950s. Just a guess, but if there had ever been a plan to revive some version of Number Please, it probably would have morphed into a whole different style of play. Number was an idea that worked, but it had no excitement. I would be interested, too, to hear if Mark ever gave the format another thought.
