It might be ripping off Kings Island a bit, but add a Coney Island section to Michigan's Adventure.  I'd add a Skywheel, like the double Ferris wheel that used to be at Cedar Point (a few carnival companies own one), maybe a Wonder Wheel clone.  I'd bring in Olympia Looping or Arie Force One (if it has to be something still around).  Then, make a cool throwback Nathan's Hot Dogs.

Many other choices, including the Haunted Mansion from Kennywood, a Zipper, Demon Drop, Rotor, lots of coasters that would have to be rebuilt.

You could convert that whole area pretty easily. Move the basketball shootout game and expand the petting zoo, convert the rest of the games into a county fair feel, and incorporate the Mad Mouse. You could extend the area to the scrambler as most of those rides have a county fair kind of vibe. It would be nice and polished without much effort, the bumper cars and log flume would create a barrier to make the area feel like its own land.

While I'm redesigning the park.... area in front of Train station would be a cool Old West/Yukon area by just adding a few facades and maybe a haunted house and/or saloon.  Antique photos are already there
