This is probably a troll but I am bored so here goes. No, there is nothing like what you are looking for. There are many wonderful and beautiful hiking trails but sport rappelling is not a recognized activity at the Gunks. For what you want try the canyons of Utah.
If you just want to hike then you will have a spectacular time. The trails at the Gunks are well thought out, meticulously maintained, and have beautiful views.
