My opinion:

If you have the weight distribution hitch, transmission cooler, proper brake system set up properly, and a hitch rated for the weight, I think you could give it a try. Take it easy, especially at first. You should get a feeling pretty soon as to whether it's adequate or not. That's the thing with trailers, you'll know pretty soon just by feel whether you vehicle is adequate or not.

Problem is you just listed a bunch of things he probably doesn't have.

Not sure about the hitch, but I kind of doubt it.
Transmission cooler? Not likely on a minivan rated to to 3500 lbs
Proper brake system set up properly? Well he's already over the rated towing capacity, so adequate braking is not at all a certainty.
Hitch rated for the weight? Nope, already over.

Could he do it? Maybe.

Is he risking wrecking his tranny, wrecking his suspension/brakes, getting in an accident, and possibly having his insurance policy voided? Absolutely.
