Have you looked at the E3D tool changer design? It uses a cantilever bed running on a single wide linear rail.

a few comments:
1) cantilevered beds usually bounce a lot, which limits print speeds to those that don't excite resonance. End supported Z axis rails contribute to the problem by flexing. Using fully supported linear guides is better.
2) why do you care how much it weighs?
3) Leveling the bed with 4 screws is unstable. Use 3 screws for set-and-forget leveling. The bed support structure will be triangular, not square- simpler and less weight (not that that matters much). The Cubex and CubePro printers by 3Dsystems used a bed support similar to what you want to do with 5 mm thick aluminum webbing:
If you want more detail of that, there's a complete CAD model of the printer here: [mark.rehorst.com]
You'll need to run DesignSpark Mechanical (free) to open it.
