If they're doing a Quiddich field, I would hope it's trackless Kuka Arms spinning and swerving around each other...
Although that won't happen. The Forbidden Forest really only has Bane (the Centaur), Aragog, and Grawp. Maybe the Thestrals could be there and a dragon. It would be perfect for a Kong style ride... But it's another Kong style ride.
That's the "problem" with the Hogsmeade area. Nothing of consequence happens there, really. The Forbidden Forest has moments but nothing huge. And absolutely NOTHING happens in the Shrieking Shack aside from Pettigrew and a meeting for Dumbledor's Army.
The only good options (story/experience) for that area are Quiddich, Chamber of Secrets (which is still a slight stretch), or...
The Battle of Hogwarts. And it would allow the ride entrance to be in Hogsmeade without changing canon. Harry, Hermione, and Ron meet with Aberforth in Hogsmeade and go through the painting to reach Hogwarts. This allows the entrance to go through Hogsmeade directly, get a magical queue experience to get back into Hogwarts for the load, and then experience the most important element of the entire series.
