So you want to put monkey bars on your boat just to have a place to have your bimini stowed while not is use? If you really won't be using the tower at all, consider a bimini frame that has all poles and no straps. Like the MC PS 197 biminis. That way you can take down the front poles, fold up the bimini, and use the rear poles as stand-up bars. I'm probably not explaining this very clear or understanding your goals but just a thought.
