I like it better as well, but I'm concerned with screwing up the structural integrity of the body and having a dangerous situation.
It seems to me that, using steel tubing, like 2x2 with a 16gauge wall, riveted and welded, running the full 20 feet back, would be sufficient. That's lets say 3' of overhang with 17 feet of the same tubing attached to the bus. But then I'm not an engineer.
I'm not too concerned with the overhang weight, because it would be about 3' or less and I would brace it up, either to the bumper, or more likely with a triangular brace to the body.
Here are some quick mock-ups I did, just to play with it.
