I'd be interested in one as well.
Maybe a design that would utilize the front tow hook mounting areas to keep it in line with the chasis.
The tow hooks could still be attached to the mount, and the receiver, would be as strong as the rear bcause it is mounted directly to the frame.

As far as sticking out. I don't think it would be that much of an issue. better protection from parrallel parkers if you want to know the truth.
