Everyone is proud of what they have done successfully. That doesn't mean its a good idea.
The starting point is that no car, which is what a GC is, will ever be a good tow rig. And, towing a rig that weighs as much as your towing vehicle, is never going to be fun. Cap that off with the wheelbase of your GC being all of what, less than 10 feet, when your trailer is twice that length and no one will be able to say that you have hit upon a good idea. Will you and your new GC survive the experience? Sure. But, it is just not a happy combination.
