Well, in 1998, GSN reruns of MG were popular, but nowadays, it's a very well-known show on the network, along the lines of some of the stuff on say, TV Land or another mainstream cable network. I think the potential producer of this one would keep that in mind, and not go for the "sex sells" route of the 98 version.
And honestly, the Marathon version of MG wasn't that bad. I actually found it to be one of the better shows, it just needs civilians and a smaller budget.
Say, MG PM format, with two $250-500-1000 Super Matches, no Star Wheel. $20,000 is still a lot of money for a daily game show.
