Personally, am thinking that designers at DC are going to have to do licensing deals with AM General to get access to their suspension design for use on future Wranglers.
As for the Hummer "look" on a Jeep - dunno, Hummer looks like they might already be trying to make some kind of SWB "Jeep" Hummer in a few years anyway.
For Jeep drivers, You'd probably be happier adopting some of the Hummer tech rather than the Hummer look.
