There was an idea floated in the early 2010s to do an overlay network over IPv4 that did this just: https://seam.cs.umd.edu/EnhancedIP/index.html

It "died" as an Internet-Draft: https://datatracker.ietf.org/doc/html/draft-chimiak-enhanced...

I don't see how this has any advantage over just deploying more NAT like people are already doing. Plus it adds IP options which routers hate.

They claim "EnIP supports end-to-end connectivity, a shortcoming of NAT, making it easier to implement mobile networks." but I don't see where mobile network operators would care about end-to-end connectivity?
