With the way IP Routing works, every router on the path makes a routing decision. So two people on the "new IPv4" would be unable to talk to each other if even one router on their path doesn't understand the new format. Not to mention that to be fully compatible, you'd need a way for a person with the address "0.1.192.168.1.10" to talk to an IPv4 only client on 192.168.1.10.
Then there are switches and routers that make assumptions about incoming packets, so we can't do strange bit hacks with IPv4 packets. http://seclists.org/nanog/2016/Dec/29
Switching to a new protocol is the only real choice at this point.
