There have been no experiments to show why this is any better than IPv6 given that you still need to modify routers and end user devices to route traffic, nor does it address the fact that IPv6 has additional features such as flows and prioritization to handle the modern Internet's traffic requirements.

The scheme you propose had already been proposed by Elad Cohen, but with "evil" intentions as they're linked to a IPv4 misappropriation scheme[1].
