Hmmm. That's a thought for a design frame engineer. If they could create a wheel/hub and frame that works together, almost like the rear frame member clamp onto and hold a caged bearing and the axle could spin inside with the rear cog outside of the stay? Maybe really narrow stays? Out of my league though...
