Crazy idea

Crazy idea. I like the torsion bar set up on my duster. To the point of saying I don't see the need for a coil front. That being said my mind is focusing on rear suspension now. And I find myself thing, if I don't want/need a coil front end, why replace the leafs with a coil rear??? Now this might sound crazy of me, but does anyone think a rear torsion bar system would be possible? And if possible, would it offer any advantages over leafs or a coil over street lynx style rear.

I'm not saying I would do it, I'm just interested in the discussion.
