Custom Side Windows

Has anyone ever seen the side windows of a Tahoe/Suburban open like the rear hatch window does. I have a two door Tahoe and use the cargo area with the second seat down and it's really hard to get to some of the tools and stuff back there from the rear door or side doors. I thought it would be cool if the side windows could be made to open up like the rear hatch which would give me access to those hard to reach areas.

Just trying to figure out how I would go about doing this? Anyone seen a conversion kit or a glass shop do it?
