That protocol already exists and is installed on almost every personal 
computer in the world... but there's alas there's still a lot of TCP out 
there.

By the way, the problems you listed are some, but not all, of the 
reasons why it isn't really a viable multi-homing strategy... but yours 
also include some of the reasons why having ULA + globally-routed space 
both active would be a problem for many applications.
