Its not just the "fan boys" that would enjoy this, if done correctly. There are a lot of parents & grandparents that don't partake in all of the rides, and are sitting around waiting for others in their party to get done with the latest attraction. The Tower Gardens was once such a nice area and has a ton of potential as a meeting/waiting area. Put some kind of history in there, heck even add a "classic KI gear" store in there where you can by "The Bat" "I learned to drive on the Ohio turnpike " (or whatever the classic car ride was called) and "King Cobra" t-shirts, replicas of old park maps, classic photos, etc... and you've got a nicely themed area of the park that would be worth visiting. What percentage of the park visits the park every season, but only once or twice a year? It would be worth stopping by at least once. Change up the stuff in there every season, and now its a place worth checking out at least once a year. Its not something that will solely get someone coming to the park the way a new roller coaster would, but if done right it could greatly enhance the experience of the average visitor, allowing them to connect with their past. Sell a few tshirts and old maps and you might actually make money off the thing. Get a grandparent that has spent the day taking their 5 year old from columbus or lexington on boo blasters and The Beastie to spend a few minures reliving the past with their grandchild explaining all the rides they used to conquer as a child, and maybe you get that 5 year old to start bugging their parents for a season pass and regular visits down the road.
The park has 40 years of memories, most wonderful, with strong ties to people of all ages. People rarely complain about a trip down memory lane, capture it and sell it. At the least, do something with the tower gardens, its such an eye sore, and as a smoking designated area, my regular wednesday evening trips last year rarely found many smokers hanging out around the leaf filled, dryed up water feature.
