Bart,

No doubt it can be done but I'm not sure you'd be happy with the results. There will be structural members behind the trim that will make your interior look like the inside of a cargo aircraft when you're done.

My guess is that you'll end up with a significant increase in road sound inside & that your sound system will suffer as well (mental image - Rolling Stones playing a concert inside a steel quanset (sp?) hut).

Just my .02
