If you want to redesign IPv[4|6] into IPvNG that deals with all known 
issues - more power to you. But do you really think we can have fully
working prototype and set of RFCs from WG by the time we ran out of
IPv4 addresses?

One of the lessons learned from IPv6 is actually that it takes long
time to agree on changes to TCP/IP stack and even longer before those
changes begin to appear on end-devices. Another lesson is that any
new type of "address" also has associated allocation policy issues
and to get consensus on that in entire world is also very difficult
and takes just as much time.
